I cannot really explain why your program doesn't work and, in fact, I
since there is not SEGFAULT it seems that this is not a bug in Gtk2Hs in
the sane that you would get the same error if you had written the
program in C.
Maybe you should follow the advice
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error()
function.)
and run the whole thing in gdb in order to understand what happened
before the program crashed.
Cheers,
Axel.
