Comment 8 for bug 848605

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.
