Comment 2 for bug 1070298

I've updated background error handling in master so it'll be less irritating in situations like these, and there will be a new PPA build available shortly at https://launchpad.net/~achadwick/+archive/mypaint-testing. Guess we need to build for Quantal now too!

Without knowing what new error message is being shown by the crash notifier, I can't help you with the new problem. I would suggest double-checking your libgdkpixbuf installation, which means ensuring that the right loader library is understood for PNGs by running

    $ gdk-pixbuf-query-loaders | less

and searching for a snippet like (Debian machine):

    "/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-png.so"
    "png" 5 "gdk-pixbuf" "The PNG image format" "LGPL"
    "image/png" ""
    "png" ""
    "\211PNG\r\n\032\n" "" 100

If necessary, rebuild the loader cache by running

    $ sudo gdk-pixbuf-query-loaders --update-cache

I'm not certain why we use the term "crash". Perhaps it's because it's more widely understood than "handled exception".
