networkmanager hostname woes

Hi Guix,

since the change to networkmanager, I've been running into the following problem: when I connect to a wireless network using networkmanager, I can no longer start graphical applications (starting any program fails with “cannot open display :0.0” and similar messages).

AFAIU, the cause is that networkmanager changes my hostname (after DHCP?), in my case to “new-host2” or something similar, and this seems to break the X session. When I manually restore the hostname with “sudo hostname <original-hostname>”, the problem is solved. Is there anyway to disable this behaviour for networkmanager?
