GSM modem enable failed: (32) Failed to find a usable modem character set

Hi,

I asked for a generic debug mechanism for network-manager / 
modem-manager. The reason for my request is that we get a big number of 
different connection issues with network-manager / modem-manger.
One of the problem is now reproducable by me. When trying to bring up 
the 3g based systemconnection I get the following error:

GSM modem enable failed: (32) Failed to find a usable modem character 
set

I have put the full debug output on pastebin:

I'm using the following versions:

network-manager	1:0.8.1~git.20100526t083526.8bd5168-1
modemmanager	1:0.3.1~git.20100525t222447.6c3ae7d-1

Thank you!
