After upgrade from OO-2.4.0 to 2.4.1 it started to crash. Different people
experience different crashes both on x86 and amd64 and also both with binary and
built from sources version. The common in this bugs was that
OOO_FORCE_DESKTOP="none" fixed the issue. For reference see out bug: 
http://bugs.gentoo.org/show_bug.cgi?id=225853

I've build OO and libX11 with symbols and here is backtrace:
(gdb) c
