Konqueror display directory, invokes libart, which bombs with an assertion failure
Last modified: 2008-05-06 15:16:10 EDT
Description of problem: ======================= I want to run Konqueror to display a directory contents. Konqueror invokes libart to draw an icon for a zip file using a SVG file, in this case /usr/share/icons/gnome/scalable/mimetypes/tgz.svg which belongs to gnome-icon-theme-2.16.0.1-3.fc6 (see below). Drawing sadly fails with an assertion error (maybe the SVG file is bad?) Version-Release number of selected component (if applicable): ======================= libart_lgpl-2.3.17-4 kdebase-3.5.6-0.1.fc6 gnome-icon-theme-2.16.0.1-3.fc6 (apparently the culprit) How reproducible: ======================= Always Steps to Reproduce: ======================= 1. Start Konqueror 2. Use large icons 3. Display a directory with a Zip file in it, so that a large icon for a Zip file must be used. Actual results: ======================= Konqueror crashes with assertion failure: konqueror: art_render_gradient.c:338: art_render_gradient_linear_render_8: Assertion `offset_fraction <= stops[ix].offset' failed. Expected results: ======================= Directory kontents should be displayed. Additional info: ======================= Stack trace at crash time (not much use): #0 0x001d9402 in __kernel_vsyscall () #1 0x00202d40 in raise () from /lib/libc.so.6 #2 0x00204591 in abort () from /lib/libc.so.6 #3 0x001fc38b in __assert_fail () from /lib/libc.so.6 #4 0x007ae45b in art_render_gradient_radial () from /usr/lib/libart_lgpl_2.so.2 #5 0x007ac3fa in art_render_invoke_callbacks () from /usr/lib/libart_lgpl_2.so.2 #6 0x007aefa4 in art_render_svp () from /usr/lib/libart_lgpl_2.so.2 #7 0x007b4676 in art_svp_render_aa () from /usr/lib/libart_lgpl_2.so.2 #8 0x007af0ca in art_render_svp () from /usr/lib/libart_lgpl_2.so.2 #9 0x007ace6e in art_render_invoke () from /usr/lib/libart_lgpl_2.so.2 #10 0x030f5d07 in KSVGIconPainterHelper::applyLinearGradient () from /usr/lib/libkdecore.so.4 #11 0x030f65ae in KSVGIconPainterHelper::applyGradient () from /usr/lib/libkdecore.so.4 #12 0x030f6a52 in KSVGIconPainterHelper::applyGradient () from /usr/lib/libkdecore.so.4 #13 0x030f71e3 in KSVGIconPainterHelper::applyGradient () from /usr/lib/libkdecore.so.4 #14 0x030f78a6 in KSVGIconPainterHelper::drawPathInternal () from /usr/lib/libkdecore.so.4 #15 0x030f7b1c in KSVGIconPainterHelper::drawVPath () from /usr/lib/libkdecore.so.4 #16 0x030f05fe in KSVGIconPainter::drawRectangle () from /usr/lib/libkdecore.so.4 #17 0x030e849a in KSVGIconEngineHelper::handleTags () from /usr/lib/libkdecore.so.4 #18 0x030e880b in KSVGIconEngineHelper::handleTags () from /usr/lib/libkdecore.so.4 #19 0x030e880b in KSVGIconEngineHelper::handleTags () from /usr/lib/libkdecore.so.4 #20 0x030e53d3 in KSVGIconEngine::load () from /usr/lib/libkdecore.so.4 #21 0x030079d6 in KIconLoader::loadIcon () from /usr/lib/libkdecore.so.4 #22 0x03700a43 in KMimeType::pixmap () from /usr/lib/libkio.so.4 #23 0x0372c39f in KFileItem::pixmap () from /usr/lib/libkio.so.4 #24 0x009a427b in KFileIVI::KFileIVI () from /usr/lib/libkonq.so.4 #25 0x00ced2e0 in KonqKfmIconView::slotNewItems () from /usr/lib/kde3/konq_iconview.so #26 0x00cf4b98 in KonqKfmIconView::qt_invoke () from /usr/lib/kde3/konq_iconview.so #27 0x05adcbea in QObject::activate_signal () from /usr/lib/qt-3.3/lib/libqt-mt.so.3 #28 0x03730fd9 in KDirLister::newItems () from /usr/lib/libkio.so.4 #29 0x0373253b in KDirLister::emitItems () from /usr/lib/libkio.so.4 #30 0x03735ba7 in KDirListerCache::slotEntries () from /usr/lib/libkio.so.4 #31 0x03739585 in KDirListerCache::qt_invoke () from /usr/lib/libkio.so.4 #32 0x05adcbea in QObject::activate_signal () from /usr/lib/qt-3.3/lib/libqt-mt.so.3 #33 0x036872a4 in KIO::ListJob::entries () from /usr/lib/libkio.so.4 #34 0x036974ab in KIO::ListJob::slotListEntries () from /usr/lib/libkio.so.4 #35 0x0369783f in KIO::ListJob::qt_invoke () from /usr/lib/libkio.so.4 #36 0x05adcbea in QObject::activate_signal () from /usr/lib/qt-3.3/lib/libqt-mt.so.3 #37 0x03676fd9 in KIO::SlaveInterface::listEntries () from /usr/lib/libkio.so.4 #38 0x03678717 in KIO::SlaveInterface::dispatch () from /usr/lib/libkio.so.4 #39 0x03679180 in KIO::SlaveInterface::dispatch () from /usr/lib/libkio.so.4 #40 0x03673fed in KIO::Slave::gotInput () from /usr/lib/libkio.so.4 #41 0x03676098 in KIO::Slave::qt_invoke () from /usr/lib/libkio.so.4 #42 0x05adcbea in QObject::activate_signal () from /usr/lib/qt-3.3/lib/libqt-mt.so.3 #43 0x05add5c2 in QObject::activate_signal () from /usr/lib/qt-3.3/lib/libqt-mt.so.3 #44 0x05e69910 in QSocketNotifier::activated () from /usr/lib/qt-3.3/lib/libqt-mt.so.3 #45 0x05afd7d0 in QSocketNotifier::event () from /usr/lib/qt-3.3/lib/libqt-mt.so.3 #46 0x05a73e6b in QApplication::internalNotify () from /usr/lib/qt-3.3/lib/libqt-mt.so.3 #47 0x05a752e9 in QApplication::notify () from /usr/lib/qt-3.3/lib/libqt-mt.so.3 #48 0x02fb156e in KApplication::notify () from /usr/lib/libkdecore.so.4 #49 0x05a67631 in QEventLoop::activateSocketNotifiers () from /usr/lib/qt-3.3/lib/libqt-mt.so.3 #50 0x05a1c1c1 in QEventLoop::processEvents () from /usr/lib/qt-3.3/lib/libqt-mt.so.3 ---Type <return> to continue, or q <return> to quit--- #51 0x05a8d3f0 in QEventLoop::enterLoop () from /usr/lib/qt-3.3/lib/libqt-mt.so.3 #52 0x05a8d2a6 in QEventLoop::exec () from /usr/lib/qt-3.3/lib/libqt-mt.so.3 #53 0x05a7397f in QApplication::exec () from /usr/lib/qt-3.3/lib/libqt-mt.so.3 #54 0x00a39a74 in kdemain () from /usr/lib/libkdeinit_konqueror.so #55 0x08048472 in ??
