I realize that the suggestion I wrote about undoes a security fix. So,
don't do what I said, do something different (what about going outside
and enjoying a walk?). Well ok, the issue said to be fixed is only a DoS
(of course ironically it introduces another DoS ;).
Thanks in advance to the security team for fixing the fixes.
Thanks,
Christian.

Today I did the usual dist-upgrade for my "testing" install, and it
left me with a badly broken (from user's perspective) installation,
because basically all Gnome applications stopped working. After a bit
over 2 hours worth of investigation, I've found out how to solve the
issue; since I first looked here and didn't find anything gnome
related, I'm sending this to the list for the casual other victim.
Symptom: Gnome apps just hang, without outputting anything to
stdout/stderr (or .xsession-errors if started through the menu).
Problem: the apps segfault inside libxml2, and thereafter enter a
deadlocked state in a mutex (or in a select call); the former is
apparently a bug in libxml2, the latter seems to be the Gnome
functionality to pop up a windows which seems to have an issue on it's
own (so it's really two bugs happening here, obscuring the
investigation a bit.)
Solution: install libxml2 from unstable; this is actually a downgrade
(from libxml2 2.6.32.dfsg-2+lenny to 2.6.32.dfsg-2). I.e. "apt-get
install -t unstable libxml2/unstable", but you need to have the
unstable sources in apt.sources and use apt pinning (I won't explain
that here, check other sources).
Cheers,
Christian.
