I wanted to fix that one today but couldn't reproduce it (although I
really tried hard). Due to work on video support, there were
substantial changes in the media package lately, so I suspect some of
them had an impact on the deadlock that was causing this issue.
Before we close it however, could you please try it out again and see
whether you are still having it? I don't want to be wrongly
proclaiming it as fixed once again
