Comment 4 for bug 249857

I confirm this bug. Just happened to me.

And there's really not much to see, the interface just freezes. The core seems to be otherwise working (downloading files, etc.), but the interface is hung up.

I'm going to attach a debugger the next time I catch it.

The CPU doesn't go high, so I'm guessing it's not an infinite loop. Also, as files seem to continue downloading, perhaps a misplaced semaphor/mutex signal ?
