compiz crashed with SIGSEGV in CompAction::initiate()

[Martijn vdS]

I clicked the icon for my browser in the bar on the left side to un-minimize one of the two browser windows (the other one was already visible). Nothing seemed to happen, and then Compiz died and was restarted.

Just had the same issue with two Steam windows. Just as it says in the original report, one window was minimized and one was visible. When I clicked on the icon, my desktop froze for a few seconds and Compiz crashed.

I have the same problem when I clicked the icon of nautilus browser on the dashboard on the left side.
This problem is disappeared when I try repeat the same actions twice.

Not a lot of information to add, but from my experience this crash happens randomly. I mean, it is when an icon with more than one window opened is clicked (when it would scale the windows from that program down and show all of them so I can select one), but sometimes I go days without a reboot and without seeing this crash, and just now it happened, and I had rebooted less than an hour ago. So far I couldn't isolate a situation that seems to trigger the bug: it has happened to me with different applications (i.e. it doesn't happen only on a certain icon).

This is happening in 14.04 for me
