It seems that the problem is known in the XCB community, and does *not* occur with libxslt 1.1.17. :( http://lists.freedesktop.org/archives/xcb/2006-November/002370.html
Being dealt with upstream. This is in no way specific to Fedora http://bugzilla.gnome.org/show_bug.cgi?id=378766 Also note that there is a libxslt-1.1.19 in Fedora Testing updates since Nov 29 so a minimal thing to do is test the updates first. If you don't want problems being detected after release, used the CVS versions regulary, there is a CVS snapshot generated every hours, and anonymous CVS access... so please take that ':(' back, thanks, Daniel
