deja-dup-monitor fails backup to smb, while deja-dup itself succeeds (error resolving server name)

[Stephan Burkhardt]

I have a backup location on a Samba share, which is reachable under an URL of the form
smb://MyGroup;myname@myservername/myname/deja-dup

Backing from the main Gui (using "Backup now") or using "deja-dup --backup" from the commandline works without problems. However automatic backups do not work. If I start deja-dup-monitor by hand, I get the following error whenever it tries to perform a backup:

** (deja-dup-monitor:22068): WARNING **: Network.vala:48: Error resolving 'myservername': Name or service not known

This seems to happen in the function can_reach, which itself seems to call the GTK network library. I already checked whether the function is called with the correct url by inserting a bit of debug code into the can_reach function, and it does indeed use the correct url. So the error IMHO seems to be on the network library side.

Ubuntu Release:
Ubuntu 13.10

Deja-dup Package:
27.3.1-0ubuntu1 0

Additional Information:
I use the KDE Desktop environment (4.11.2) and the passwords are to my knowledge all saved in the KDE Keyring (KDE Wallet Manager).

What I expect to happen:
I expect the automatic backup to an smb share to work
What happened instead:
Automatic Backups are not performed and I always have to initiate the backup by hand.
