This looks like its a race-condition, maybe with the update-software-center-agent process. What is puzzling is that the code is not doing any glib event processing so the for loop should have a valid db.

Is this reproducable for you? Can you outline the steps that triggered the crash? Was it just enabling recommendations and after that it crashed?

[Trond Aasan (trond-aasan)]

It crashed after enabling recommendations.

I have done an apt-get distupgrade since the crash.

No crash now, it just says "Submitting inventory" forever, with no network activity.

[Michael Vogt (mvo)]

Thanks Trond for this additional information. You will have to close/ropen it again for the "submitting inventory" to go away.
