It's an error in JpegImageInput::finishImage(), called in the destructor of JpegImageInput to clean up after reading normal images. I'll commit a fix to both abort and segfault in a bit.

The attached jpeg was found in swfdec testsuite, loaded by
trace/oversized-image-*.swf togheter with another image.

The first image (wookiemon.jpg) doesn't crash gnash.
The second (cookiemon.jpg - attached) does.

You can pass it directly to gnash, it's enough to trigger
the crash. It actually aborts due to unhandled OOM exception
but if you catch the exception you still get a segfault.
