xine 1 has a new video processing API, which should be much more reliable than
the old 'give-me-last-frame' API. It should now be possible to implement the
algorithm originally intented for the video thumbnailer.
The algorithm consisted of reading frame 1, 2, 4, 8 ... until there is enough
variance in the pixel brightness of the current frame. This should probably
be limited to some maximum stepsize and no more than a few seconds of video
for performance reasons (see "videocreater.cpp" by Simon MacMullen).

The default xine ui doesn't create thumbnails, but the snapshot feature of the
xine ui could cause the same problem (in theory). It would also be much
better to use the xine libraries directly and not through the aRts server for
creating video thumbnails (IMHO). This should provide some protection against
the problem you described.
