[Bug 1028640] Re: session-installer crashed with TypeError in _on_property_changed(): could not convert type dbus.Array to PyObject required for parameter 0

[Steve Langasek]

Marking as 'high' because this is the single most frequent crash
reported in 12.10 right now.

Was going to mark this for SRU as well, but it looks like there isn't
actually any evidence of this crash occurring with 12.04; so it's
probably an aptdaemon behavior change (as the backtrace somewhat
suggests), and not a bug in sessioninstaller at all.

** Changed in: sessioninstaller (Ubuntu Precise)
       Status: Triaged => Invalid
