tumbler crashes on broken png files

[raphgro at web.de]

I monitor a lot of tumbler crashes when I browse in Thunar with Fedora 16.
A crash appears nearly every time when I change a directory, or delete a file, etc. A clear description how to reproduce the crash is in processing.

For now, please look at the downstream bug report. I don't know if this bug is already know to upstream.
