Version: 3.4.2-1<br>
Severity: important<br>
<br>
Dear Maintainer,<br>
<br>
I am finding that GNOME Shell freezes fairly frequently on my workstation.  By freeze I mean that the mouse<br>
pointer still moves but no interaction causes any activity to GNOME Shell: the only key combinations that have any<br>
effect are Ctrl-Alt-Del and Ctrl-Alt-Back – I have enable Ctrl-Alt-Back as the X killer. Although GNOME<br>
Shell has frozen, the machine is otherwise running normally, i.e. if I login over SSH from another machine, the<br>
workstation is processing normally, it is just GNOME Shell that has cease responding.<br>
<br>
The problem is not a timing one, e.g. every two hours, sometimes it is a couple of days, sometimes 10<br>
mins. It is always associated with a "mouse to top-left" from desktop i.e. changing from desktop to GNOME<br>
Shell. I cannot be sure if the super key has the same problem, as I tend not use that, but I will<br>
experiment. I believe that the GNOME Shell freeze only ever happens when Evolution is an application on the<br>
current desktop. Clearly I need to do more experimenting to get more data, but it would be good to get<br>
guidance on what would be the very best experiments to maximally help find the problem.<br>
