compiz crashed with SIGSEGV in Launcher::UpdateIconXForm()

[Stephen Rees-Carter]

Binary package hint: unity

I don't really know what caused this one.
It could have something to do with this bug https://bugs.launchpad.net/ubuntu/+source/unity/+bug/738448 , but it could also be completely unrelated.

It was reported due to my problems reporting that bug (see https://bugs.launchpad.net/unity/+bug/737928 for more details)

[Jason Smith (jassmith)]

The stack appears to be well smashed. :/

Can you check your memory with memcheck and try to find steps to reproduce?

[Omer Akram (om26er)]

Could you please provide what Jason inquired.?
