Re: [gtk-list] random crashes (my code)

["Jason A. Pfeil" <pfeil nu cs fsu edu>]

A problem in malloc usually means you have a pointer problem.  You may be
passing an invalid or uninitialized pointer to a function.  A code snippet
where you are creating the pixmap would be helpful, since that is what
leads to the segfault.
