Hello,
could you try what the error message suggest you to do:

(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 GDK_SYNCHRONIZE
environment
variable to change this behavior. You can then get a
meaningful
backtrace from your debugger if you break on the
gdk_x_error() function.)
Program exited with code -5
With that you should be able to run your program in gdb and get a
backtrace.
However, BadAlloc sounds to me as if your program is running out
of RAM and as such can't allocate more memory.
