I can reliably reproduce the behaviour (the steps are sufficient, but not all may be necessary):
1. Grab a screenshot 2. Crop to a small part of the image 3. File->Save as... and save to a png with default settings 4. Ctrl-Z do undo crop 5. Crop to a different part of the image 6. File->Save as... and save to a png with default settings The second file will be saved, then gimp crashes. I attach a gdb backtrace with debug symbols. ** Attachment added: "gdb.log" https://bugs.launchpad.net/ubuntu/+source/gimp/+bug/1051877/+attachment/3319985/+files/gdb.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1051877 Title: invalid cast followed by double free To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gimp/+bug/1051877/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
