[Pkg-libvirt-maintainers] Bug#523637: virt-manager: deleting and re-creating a guest throws trace

[Andreas Unterkircher]

Package: virt-manager
Version: 0.7.0-1
Severity: normal


Re-creating a previously deleted guest basically succeeds but
shows up an error message. It is reproducable by following:

1. Create a guest called 'test'
2. Delete guest 'test' (regardless if or not keeping the diskfile)
3. Create again a new guest called 'test'

It works, but the following error gets displayed:

[Sat, 11 Apr 2009 17:06:47 virt-manager 25389] DEBUG (error:76) Uncaught Error: Error bringing up domain details: 'NoneType' object has no attribute 'get_driver' : Traceback (most recent call last):

    self.connections[uri]["windowDetails"][uuid] = details
UnboundLocalError: local variable 'details' referenced before assignment
None

By choosing another name for the guest, the error does not appear.
Also deleting 'test', restart virt-manager and re-create it does
not show up this.

Maybe some var's are not cleaned up correctly or so...

Cheers,
Andreas
