Is it a common issue or just happens sometimes?

Could you try with the development version?:

it happens every now and then - i'm not sure about exact steps to reproduce it.

tried with the development version, no exception so far. the "best" i could get - prev/next image buttons would get disabled :)

It was a weird download bug, happened when multiple downloads are made. The problem was that there where several objects representing the same image. It should be fixed in the development version.
