right.  i suspect that the problem is not in the compiz binary but one
the libraries or plugins shipped in compiz (most likely libcompizconfig,
which is linked to by both compiz.real and ccsm)

okay, nothing out of the ordinary there (even cleaner than my system:)

nothing out of the ordinary here either from what i can tell.

sorry, i kinda blurred what i meant: s/window manager/desktop
environment/.   in other words, what do you choose when you log in on
your system before you start compiz?  are you starting vtwm and then
compiz via an .xinitrc, or...?

okay, so the first relevant stack frame seems to come from libcompizconfig.
i'll see about providing a debug version of this library.  it might also
be helpful to get a copy of the actual core file, though there are
privacy implications as environment variables and memory contents might
be stored in this file so you probably shouldn't post it publically.  do
you think you could privately email me a copy of one of them?
