Description of problem: Screensaver module "Drempels" does not work on a current "rawhide" system sporting an "ATI Technologies Inc Radeon X800 SE (R430) (PCIE)" video card. The screen remains black, and ABRT reports a crash every time "Drempels" is called. File .xsession-errors then contains an appended line which reads "handle_message(member:'Crash')" Version-Release number of selected component (if applicable): rss-glx-0.9.0.p-3.fc12.x86_64 How reproducible: Always. Steps to Reproduce: 1. Choose screensaver module "Drempels". 2. Lock screen. 3. Unlock screen. Actual results: Screen stays black, and upon unlocking the screen again, ABRT reports a crash in "Drempels". Expected results: Screensaver "Drempels" is functional without crashing. Additional info: Other RSS-GLX modules like "Juggler3D work as expected.
Hi Joachim, can you run drempels from the command line ("rss-glx-drempels") and generate a backtrace (or does ABRT generate one which you could attach)? Thanks.
ABRT does generate a backtrace but due to bug 529583, it is impossible to upload it to https://bugzilla.redhat.com, and there seems to be no means either to save it locally before attaching it here. Anyway, running 'rss-glx-drempels' from the shell gives: $ /usr/bin/rss-glx-drempels rss-glx-drempels: radeon_texture.c:87: radeonFreeTexImageData: Assertion `!image->base.Data' failed. Abort (core dumped) According to http://bugs.freedesktop.org/show_bug.cgi?id=24325#c1 this issue has been fixed in Mesa git.
This module appears to be a dangerous one: on a second system with an "Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device rev 3", "drempels" simply locks up X completely, although it is still possible to log in from a remote system and to reboot it in a controlled manner.
