Created attachment 166526 [details] file that will crash Gwenview when you try to open it SUMMARY The file in question is probably corrupt, but this should not segfault Gwenview. STEPS TO REPRODUCE 1. Open attached file in Gwenview. (Alternatively, if you have a valid PNG file and this file in the same directory, and no other image files, opening the PNG will also crash Gwenview, probably because it tries to pre-load the other file.) OBSERVED RESULT Segfault. See backtrace. EXPECTED RESULT No segfault.

The file is fine fitstopnm will create valid images out of it, sadly we don't understand it
