KDiff Bug 436958

[Michael Reeves]

Yeah the code your getting is out of sync with git. That crash is in a qt
function that is not directly called by kdiff3. The is visible sign of how
its getting called at that line number. In any event I'm about to push a
fix for the originating issue. Try building with CMAKE_BUILD_TYPE=Debug.
If that fixes the problem then the patch will resolve your case as well.
