Comment 7 for bug 360199

Version: r954046 (using Devel)
Compiler: gcc version 4.3.3 (GCC)
OS: Linux
Installed from: Compiled sources

I walked through the images in a directory using the next and previous buttons. I changed the description of several (in the info tab), rotated several and deleted several (some using "Delete" and some using "Trash" from the Ops tab). Some of the ones I deleted I had already rotated. At the end, I clicked "Save All". Gwenview crashed (SIGSEGV), but not before all the rotations had been applied.

Backtrace: 11 threads total, 10 in wait condition.
