[Nautilus-list] Nautilus crashes when trying to generate thumbnail for invalid image file

[Dan Hensley <dan hensley home com>]

I just submitted this to bugzilla.eazel.com, but I thought I'd send it
to the list in case no one's checking bug reports there right now.



My digital camera's battery died while I was trying to download some
images (saved as .jpg).  Whenever I try to switch Nautilus to view the
directory to which I was saving the photos, it crashes.  Here's a
backtrace:


Delayed SIGSTOP caught for LWP 8442.
