Shutting down a guest while viewing the serial console hangs virt-manager

[Simon Déziel]

When using virt-manager from Precise to control libvirt on Saucy, shutting down a guest while viewing the serial console hangs virt-manager (100% CPU).

Closing virt-manager gives those warning (full debug output attached along with the guest definition):

2013-11-14 15:00:50,308 (manager:184): Closing manager

2013-11-14 15:00:50,391 (engine:550): Exiting app normally.

Since I don't have a virt-manager install running on Saucy, I cannot check if this behavior occurs only when controlling specifically from Precise.
