Wingpanel crashing randomly

[Kaan Kölköy]

I still cannot find that why it is happening but wing panel crashing randomly, I can notice it when time do not change and I can't click anywhere of panel. At this time, wing panel can use %25 CPU and I've to end wing panel process and let it start itself.

It is usually happening while virtualBox is running.

Same here , wingpanel is allways stop responding or have several malfunctions. A few time later it works again.

Also can confirm. Just installed Loki, I'm going through the usual setting up of apps and stuff, and wingpanel is crashing quite often.

[Lucas Chigami (lucaschigami)]

Just installed Elementary OS Loki, and Wingpanel crashing randomly.
Looking the syslog file, this is what is printed:

Can you confirm you have seen this issue on a fresh, up to date, Loki stable install?

[Luís Henrique Faria (luish-faria)]

I have the same problem. It's not a fresh install and the problem started last week.

I notice that using a guest account the problem doesn't happen. May is something on my profile, but I don't know what

[Luís Henrique Faria (luish-faria)]

Sorry for too much posts (can I edit?).
In my case I found the problem. I opened dconf-editor and search for options that were different from the default. After testing a few things the "input-feedback-sounds" was enabled and when I change it the wingpanel stop crashing.

Same problem on Elementary Loki now.
