Notifications indicator causes segfault

[Matt Woodmass]

November 11 I installed a system update via the Software Center. After restart wingpanel does not appear anymore. I tried starting manually from terminal with no success:

I tried sudo apt-get install --reinstall wingpanel with no success.

Not sure if this is relevant, but after the update a diaog popped up asking me to disable UEFI boot, which I ignored. Dialog appeared as part of reboot, so I went for it hoping it would fix my wingpanel issues. No success.

Hello,

Can you run wingpanel from the command line and post the output?

[Zisu Andrei (matzipan)]

Ah, nevermind, you already did that.

Can you please run "gdb wingpanel", type "run", try to reproduce the issue and then when the crash happens, type "bt" and paste the output here?

[Matt Woodmass (matt-lena)]

Please see bug description - it's already there.

The same here.

Something starts blinking in the top right corner when wingpanel tries to launch. Looks like a notification is shown and hidden immediately few times.

Same here.

Hey guys,

Can you try this branch and see if it fixes your issue?

https://code.launchpad.net/~donadigo/wingpanel-indicator-notifications/fix-g-str-hash-crash/+merge/311348

[Matt Woodmass (matt-lena)]

I actually just did a clean install and no longer have the issue.

[Felipe Escoto (philip.scott)]

The problem should be fixed with that latest branch, definitely let us know if you guys can still reproduce it :)
