[IKT (ikt)]

this happened to me but using chromium instead of firefox.

[Stephen Rees-Carter (valorin)]

This occured for me after a boot with Transmission set to auto start. Firefox wasn't event started yet...
Should I lodge a different bug, or is it likely to be the same bug?

[Lebon (remic)]

Well, in fact compiz crashes even if I close everything but deluge and add a torrent from a saved .torrent. So it's not firefox specific.

If this really is fixed I have to give you guys a round of applause, you are hammering through bugs, keep it up! =o
