But, I checked 'Preferences' and I was running 4 threads, and there's a

far, no crash.
Hi! We're trying to track down (and fix) as many threading related bugs
as we can. They're especially sneaky, so reporting these bugs helps us
greatly. Could you please file a bug report, explaining what you did to
trigger the crash? A backtrace at the point of the crash would also be
very helpful: when you run gimp under gdb, type "bt" once gimp crashes,
and include the output in the bug report.
Thanks :)

I have four threads set in preferences. The image is 16bit gamma
integer, and I try and stretch HSV contrast.
