I received a message which Thunderbird marked as junk. I opened it, and used Shift-J to mark it as Not Junk, but the green Junk warning did not disappear from the message window. I hit Shift-J again, closed the window, and opened it again. It was no longer marked as Junk (in the message list either).

Very soon after I found a "Warning: Unresponsive script" window onscreen, along with a Save Message As window for that message, although I don't recall using Save As.

Unfortunately, the "Warning: Unresponsive script" window doesn't respond at all to the mouse. The Save Message As window flickers buttons in response to clicks, Esc, and Return, but doesn't actually go away or save anything.

Reproducible: Didn't try

Actual Results:  
log4moz.js triggered an Unresponsive script message, which effectively hung Thunderbird completely.

Expected Results:  
log4moz.js probably shouldn't trigger Unresponsive script.

Unresponsive script should respond to input, and shouldn't lock up other dialogs.

Attaching sample & screenshot.

I had to Force Quit Thunderbird, although the system didn't mark it as "Not Responding".

hangs are critical.
