This may or may not be related to 166025 - I'll leave that for the experts to 
decide.

Hovering over certain .avi files causes dolphin to crash with the following 
backtrace. It is not all avi files, but the same ones always cause a crash, and 
I don't know what is different about the ones that do I'm afraid. Sorry but 
they are WAY too large to upload on my slow connection.

As with 166025 Nepomuk is turned off and simply hovering the mouse is enough to 
provoke the crash.

Best of luck, and keep up the good work.
