unity-panel hangs and uses over 100%

[Daniel Holm]

Sometimes the panel just hangs. If I click on any of the indicators, the menu is transparent and hangs. Using top I can see that the unity-panel process uses over 100% of the CPU and I have to kill it.

Thank you for your bug report, do you use skype or other qt softwares? it could be bug #865601

[Daniel Holm (danielholm)]

Yes, I am using Skype, so that could be it. It only happens when I'm not connected to internet.
