gnome-panel crashed with SIGABRT in g_assertion_message()

[Selmi]

it started to happen after upgrade to ubuntu 15.10. i never had this problem in 15.04

now after few hours of working, usually when i try to close some full screen window (mostly firefox, thunderbird) it starts to look as if i would do logout, all applications are closed and login screen appears.

I got some more similar crashes in other packages - gnome-shell and metacity. result is always the same, everything is closed, login screen appears. real problem is probably in some library shared to all of them

[Selmi (selmi)]

I think it might be related to spotify client from , in last days i noticed that it happens when i try to search something there (as soon as i try to write into search text field)

spotify client is from http://repository.spotify.com testing non-free
stable version doesn't run because of dependency on libgcrypt11.so

[Selmi (selmi)]

no, it happens without spotify as well

15.10 is end of life. Do you have same crashes with 16.04?

[Selmi (selmi)]

Yes, it happens, though I think it is not so frequent, once in several days. I will attach files from 16.04 when it will happen again.

[Expired for gnome-panel (Ubuntu) because there has been no activity for 60 days.]

oh well, i am already using unity session and somehow i couldn't force myself to boot to gnome. sorry. it doesn't matter anymore
