Gtk-- 1.0.1 cantains a bug that the insertion list used by
delete_self is not properly initialized.  This results in
a seg fault when the connection list incounters the broken 
list. (This only occurs on SGI, HP-UX, and FreeBSD.)  The
problem is caused by a library loader which can not initialize
static objects.
ftp://rtfm.mit.edu/pub/usenet/news.answers/g++-FAQ/plain 
The problem is fixed in Gtk-- 1.0.2.
Hope that solves the problem.
