Ok, I might have just been too impatient, because the last few times the session didn't drop me back on the login screen but just locked up. This time, however, after a while it did drop me on the login screen and I got a working .crash file. Reported a new bug (#1724159) with the details! --

I got another "crash" (or rather a lockup), again linked to Spotify switching to a different song (-> notification). Unfortunately, apport- retrace just gives me this: "ERROR: report file does not contain one of the required fields: Package" I googled a bit and tried adding the package gnome-shell

the interesting part is the stacktrace from the dump though, could try to use apport-retrace on it? otherwise try to clean that directory, trigger the issue again and see if there a new uptodate report that you can submit using ubuntu-bug -- You received this bug notification because you are a
