mutter crashes when closing pop-up dialog

[Matt Zimmerman]

Binary package hint: unity

I played a video in Totem, which unfortunately caused pulseaudio to crash. When this happens, totem opens a series of pop-up dialogs in rapid succession (perhaps 3-5 of them) to display error messages. When I clicked OK on the top one, mutter crashed, with the following output:

Bug in window manager: Unexpected X error: Badwindow (invalid Window parameter) serial 351839 error_code 3 request_code 20 minor_code 0)

I restarted mutter, this time with stdout and stderr redirected to a log file, and tried to close the next dialog down in the stack, and mutter crashed again. I'm attaching the full log.

Thanks for the bug report Matt.

@jassmith: didrocks also indicated that the issue does not occur in mutter without the Unity plugin loaded.

So it seems like indicator-appmenu wasn't catching xerrors properly, hence badwindow errors were propagating to mutter which wanted to bail at the first sign of trouble (wimp!). The linked branch of indicator-appmenu should make a significant difference to the stability of Unity.

I've also fixed a missing error trap in my places-fixes branch.
