gnome-shell crashed with SIGABRT in g_assertion_message()

[Colin Keenan]

I may have somehow messed up my gnome 3 gnome-shell. I can still use gnome classic without extra graphics or whatever it's called.

I was trying to report about gnome-shell using 100% cpu in this bug report I filed earlier about compiz using 100% cpu: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1044060

And, because gnome-shell was using 100% cpu, I had to kill it and restart it from a virtual console. For some reason it didn't occur to me to use "DISPLAY=0: gnome-shell --replace". Because I had just been running a dstack script in that virtual console, I was in super-user mode when I killed and restarted gnome-session.

Now, whenever I try to log into gnome 3, gnome-shell doesn't load. If I run gnome-shell --replace from a terminal window, I get the following error:

JS LOG: Error: Requiring IBus, version none: Typelib file for namespace 'IBus' (any version) not found

This is strange. I logged into Ubuntu under Compiz/Unity, shutdown, and later when I turned on my computer and logged in again, I got a bunch of error messages so went ahead and tried to report them all. One of them was this one again, which it said was a known issue. What's strange about it is that I wasn't running gnome-shell this time or last time.

I noticed today's updates included updates to gnome. After the updates and re-boot, I was able to log into gnome and gnome-shell loaded fine. That's what I'm using now. Maybe this bug can be marked as fixed released or something. Of course, I don't actually know if the trouble I was having getting gnome-shell to run has anything to do with this bug that was detected by Ubuntu automatically more than once.

Thank you for reporting this bug to Ubuntu. Ubuntu 12.10 reached End of Life in 2014. See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases

Please upgrade to Ubuntu 16.04 LTS and re-test. If the bug is still reproducible, increase the verbosity of the steps to recreate it so we can try again.

I apologize that we are not always to respond to bug reports promptly. Do feel free to report any other bugs you may find.
