Dear Michael,

Luckily this problem did not occur again. I restarted my machine after the 
fill-up which caused several programs to not respond anymore in order to 
investigate what was going on.

So no, I cannot reproduce this unfortunately.

Currently there is a modem-manager process running and everything seems fine 
again. Checking the logs reveals the following messages:

Yes it was directly after installing the updates with "aptitude safe-upgrade" 
(and modemmanager came along with them).

Maybe it was some race condition that occurred right after the update that 
caused the problem and rebooting the system (and thus restarting the network-
manager and dbus too) helped to fix it.

It was quite surprising to find my system in a (for me) somewhat unusable 
state after some updates. Furthermore I know that without being able to 
reproduce this issue, fixing it for others that install this package is tough. 
But unfortunately I cannot provide more information about it.

Best regards
