Comment:
> Did you get the backtrace while it is eating CPU?

Yes, maybe I'm doing it wrong.  Here's my 2nd attempt:

1. launch gimp, Ctrl-O to open file --> frozen now (CPU 80-100%)
2. gdb gimp $(pidof gimp)
   gdb has taken over, CPU back to normal
3. (gdb) thread apply all bt

   CPU shoots to 100%,  must kill gimp.
