Description of problem:
If I plug my laptop on its dock station which has a wired connection, MN starts as expected when I am logging on a GNOME session.
If I unplug my laptop to use Wi-Fi then MN will hang at 100% CPU.


How reproducible:
Almost always. Sometimes MN starts but it is unable to connect with a mail server.

Steps to Reproduce:
1. Unplug the network cable
2. Boot your machine
3. Open a session
4. -> NetworkManager is starting to find a Wi-Fi a network to connect to
   -> Mail-notification is starting too and it is perhaps trying to connect to a mail server whereas network is not available
5. mail-notification icon is blinking because none server is available so you have to left-click on the icon and then click on "update"
6. now your CPU usage is at 100%.

Additional info:

A attached a GDB session to mail-notification when it got frozzen:
