[xml/sgml-pkgs] Bug#439982: Segfaults in Evolution, Firefox, others (libxml2?)

Tue Aug 28 21:19:50 UTC 2007

Package: libxml2
Version: 2.6.30.dfsg-1
Severity: important
Architecture: amd64

I am experiencing random segfaults primarily in Evolution and Firefox,
most often when viewing/modifying settings (Evo) or when downloading
files (Firefox). I ran both through gdb and found they were both
faulting at __xmlParserInputBufferCreateFilename in libxml2.so.

This is a brand new install of unstable on a very new Lenovo Thinkpad
T61.  I mention the hardware because I am running unstable elsewhere and
I have not experienced this problem except on this laptop.  There is no
other indication that this may be related to the hardware, as everything
else is working normally so far except for these random crashes.

I have also rebuilt the libxml2 packages from deb-src, just to see if
that would help. I got a different backtrace, but Evo crashed just the
same.

A couple backtraces from evolution follow.  I'll try to get one from
Firefox and post it as well.
