Hi Julien,
The bug is still present if I downgrade libx11-6 to the version that is
currently in Lenny and Etch (2:1.0.3-7).
Today I upgraded to the newer OOo packages (1:2.4.1-2) that became
available on my mirror. I still see the crash on exit unless I disable
KDE integration (again with both the newest and the older version of
libx11-6).
Here is another gdb session excerpt (openoffice.org-kde 1:2.4.1-2,
libx11-6 2:1.1.4-2), in which I try to provide the additional
information that you asked for:
Program received signal SIGSEGV, Segmentation fault.
