[Bug 848605] Re: session-installer crashed with AlreadyCalledDeferred in callback()

[Steve Kroon]

I got referred to this bug by my system.  Before that, Rhythmbox had
prompted me if I wanted to install plugins, and it was trying to install
them.  This failed with the error message below.  Other possibly
relevant information: at the time this happened, the Update Manager was
open (but not active - i.e. not downloading/installing updates).

Error message:

session-installer (Window Title)

An unhandlable error occured

There seems to be a programming error in aptdaemon, the software that
allows you to install/remove software and to perform other package
management related tasks.

Details:

org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible
causes include: the remote application did not send a reply, the message
bus security policy blocked the reply, the reply timeout expired, or the
network connection was broken.
