Status changed to 'Confirmed' because the bug affects multiple users.

[Jean-Baptiste Lallement (jibel)]

reproduced by using steps from bug 903034 and using quicklist twice

[Omer Akram (om26er)]

that doesn't look like a NUX crash to me.

[Jean-Baptiste Lallement (jibel)]

I can't reproduce this problem with latest version of unity. Is it still a problem for any one ?

[Ben Prescott (ben.prescott)]

I found this via terminal (Bug #910583) and can't reproduce it on beta-1 with updates as of yesterday. Opened lots of new terminals via menu and middle click and it works as expected.

[Tim Penhey (thumper)]

I don't get this any more, and it seems there haven't been dupes for some time.
