First, you must tell your shell to allow coredumps with the following command:
$ ulimit -c 32000

Then you can run the drag & drop program inside this shell, until you succeed 
in crashing it.

Then you will get a core dump file named core.XXXX where XXXX is the process 
id of the crashed program.

Then you can run gdb on it to find where it crashed, this way:

$ gdb /usr/bin/gbx2 core.XXXX
...

gdb will tell you exactly where the program crashed. Send me this information!
