Description Milan Bouchet-Valat 2012-05-12 10:42:42 UTC 
This crash has been reported in Fedora 17. I am able to reproduce it on demand by taking a screenshot and editing it a few seconds after that using Shotwell. The crash happens when saving the modified file. So maybe tracker-extract is working on the PNG file, and it doesn't like that the file is removed during this process...

It's possible this is the same problem as we see in bug 660965 so I am going to mark this as a duplicate for now. We don't have any detailed information about PNG crashes except for this bug report. We also don't see crashes EVER with PNG files so I suspect these are related to some changes to libpng upstream.

Thanks for the bug report. This particular bug has already been reported into our bug tracking system, but please feel free to report any further bugs you find.
