(the stacktrace is from bamf 0.2.118-0ubuntu2~webapps12

I'd also like to add that I cannot reproduce this crash. The pause button is not pausing the Youtube video, but is also not causing any crashes. Perhaps the two are unrelated? I don't know.

The lines number on the stacktrace doesn't seem to match here... :o

I didn't receive this bug when using YouTube, so I don't think this one is mine.  Though I did receive the bug it apparently is a duplicate bug to the person describing what happened to them on YouTube.
