[EDGY] firefox crashed [@ pthread_mutex_lock] [@ NP_Shutdown]

[kfrance]

Binary package hint: firefox
Firefox generates a crash report even though it did not crash
Upon reboot firefox reports a crash but firefox didn't crash. This can happen every time if you don't close firefox and shutdown the system as I frequently do. Each time in the task bar I get a crash report that asks me if I want to file a bug. I have ignored it for some time but thought I would pass this along. Obviously this is not a huge deal and is probably expected but slightly annoying.

I can get you more information if you like. Just let me know what you would like.

Thank you kfrance for reporting this issue. We get from time to time this kind of reports that are always related (from retracing the coredump) with flash player. You might want to migrate your flash plugin to ubuntu's package flashpluging-nonfree because it may be more up-to-date and tested.

Let's see what the retrace says.
