compiz crashed with SIGSEGV in LauncherIcon::GetQuirk()

[Jamie Strandboge]

Binary package hint: compiz

I had several windows open (evolution, gwibber, empathy, 2 firefox windows, 4 virt-viewer windows, and several terminals). I clicked around in the launcher on firefox and then the virt-viewer icons. They had been all minimized. All 4 virt-viewer windows popped up and I tried to minimize on of them and compiz crashed. This is not immediately reproducable since I was able to perform these same actions earlier.

(updating description because I had to paste what was in my clipboard since the keyboard was no longer functional after the crash).

This happened to me again just now.

Reassigning to unity for now since it happened while using Unity.

[Didier Roche-Tolomelli (didrocks)]

Hey Jamie,

As the crash has been triggered by compiz and not unity, the stacktrace retrace isn't complete (unity debug symbols aren't installed as it's not an compiz depends). Can you try installing latest unity with dbgsym locally and get a stack manually, please?

[Jamie Strandboge (jdstrand)]

Closing since this was several compiz updates ago. If I see it again, I will file another bug.
