compiz crashed with SIGSEGV in g_closure_invoke()

[Matteo Giachino]

Binary package hint: compiz

I was trying to resize a window with the new compiz plugin "Unity MT Grab Hanldes".
I binded the plugin toggle to ctrl+alt. When I pressed it compiz crashed.

[wolfen69 (wolfen69)]

I'm using Natty 64 Unity, and compiz crashes when doing Alt-tab.

[Lars Renström (lars-renstrom)]

For me it crashes when I try to Alt+F2 on newly installed natty, 64-bit. Works fine on my other 32-bit systems.
