Package: libxml2
Version: 2.6.32.dfsg-2+lenny
After anupgrade at about 15:00 GMT+2 Aug 27 from ftp.de.debian.org, I
started experiencing crashes in various GTK programs. These failed to
show context menus, running instances suddenly crashed, new instances
refused to start. All diagnostics I could gather were "Segmantation
fault" messages. (Sorry, I did not try versions with debug symbols.)
The problem seemed to be in /usr/share/icons/*/icon-theme.cache files.
Attempts to show an SVG icon anywhere lead to a segfault. (I had an
svg-based icon theme, so switching from it to something other via GUI
was problematic; finally I edited the ~/.config/xfce4/mcs_settings/gtk.xml.)
Looking at icon directories was also problematic. Here is a typical session:
$ thunar /usr/share/icons/Amaranth/ &
[1] 7057
$ could not load face
'file:///usr/share/icons/Amaranth/icon-theme.cache': unknown file format
[1]+ Segmentation fault thunar
$ _
The SVG icons themselves were not changed for quite some time:
$ ls -l /usr/share/icons/Amaranth/scalable/actions/application-exit.svg
-rw-r--r-- 1 root root 4577 Apr 27 2007
/usr/share/icons/Amaranth/scalable/actions/application-exit.svg
Removing the /usr/share/icons/*/icon-theme.cache files seemed to solve
the problem for me, at least for some icon themes, like Lush. Other
themes, like Gorilla, still crash. A sample SVG from Gorilla theme that
causes a crash is attached.
I'm not sure that it's definitely a libxml2's fault; I only marked it as
a culprit because from xml-related packages only it had been updated
before problems began.
Here's software I run that seem relevant to the issue.
