Comment 12 for bug 486617

A work-around is to not have any unsupported file formats in the camera. If you have movies, for instance, you will hit this bug.

It's fixed in upstream with a simple patch that clears error flags that failing to produce a thumbnail sets.

That patch is already applied to gthumb trunk. If someone will make sure that it's safe to unset the error flag (for instance, is it possible to have an error earlier, for which we should not unset it if there is *another* error we want to ignore), then I think it should be safe for a Ubuntu-package patch.

Since having movies on cameras is almost the default case these days, this deserves some attention and a High or Critical severity.
