Good to know, thanks. This socket is used by fluxbox to communicate with
the X server through the X library. So it could be either fluxbox
crashing because it does not use some X calls correctly, or a bug in a X
library. It reminds me of bug #431746 where xinerama not being reported
correctly by the sever causes some clients to crash.

The next step would be to catch this segfault in gdb so that we know
where the crash occurs. Running 'gdb fluxbox' and entering 'bt full'
after the segfault will give you a backtrace (we might need to install
some debugging packages to get a full backtrace, we'll see).
