Hi Tom, if this happens with your application, and other GTK programs on
your machine are OK, it's probably a problem in your code somewhere.

This sort of thing is uaually a memory problem: you're perhaps freeing
something twice, or writing beyond the end of an area of memory you
allocated. Try running with electric fence, or try memprof.

HTH, John
