Steps to reproduce:
1. Open any window.
2. Press and hold down Alt long enough for the task switcher to render a preview of the active window.
3. While still holding Alt, press F4 so the active window is closed.
4. Compiz crashes.

The crash happened every time I use ALT+F4 to close a window!

Are there any news on this bug? Will there be a patch available soon?
Tommorow should be released the beta realease of Ubuntu Onieric and this version have a few really bad bugs. My system crashes every time after the login and every time I press ALT+F4 to close a window.

Would be nice to see a new version which fixes this bug!

It's now an old version of unity. Unfortunately, unless there is a clear way to reproduce it, it's improbable that this can be fixed in time for the final release.

Most likely it already has been fixed; I can no longer generate it.

Thanks for testing the new version. I will mark the bug invalid now, but as usual, re-open if it comes back.

How many is too many?

reopening, it is still an issue with ALT+TAB and closing a windows while the switcher is active. I'll add a test case in the description.
