I also have a similar ( if not identical bug). Occurs under heavy load. Has been ongoing for several versions. Lockup is always preceded by an identical NetworkManager error.

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.
