compiz crashed with SIGSEGV in PrivateWindow::processMap()

[Le Sy Tung]

Binary package hint: unity

While working with Mozilla Thunderbird, I usually face with screen crash and all go blank after it. It takes seconds to refresh then report a bug resulted from compiz. I don't know any thing more.

Thanks for your support.

Opening file attached to e-mail creates this "crash". E-mail client: Thunderbird.
Everything updated.

Thanks for reporting this bug and help to make ubuntu better.

However, it seems you chose the "light report" and not the "full report" upload when you got the crash. That won't enable us to debug the issue.

Can you please retrigger the crash and choose "full report" this time when the window popup?
I'll mark this bug as invalid meanwhile (it will open a new bug)
