 MB> Hm, this should be fixed since 0.9.1.95-1.

My network-manager history, from /var/log/dpkg.log:

2011-11-19 20:56:26 install network-manager <none> 0.9.0-2
2011-11-19 21:03:52 configure network-manager 0.9.0-2 <none>
2011-11-19 21:03:53 status installed network-manager 0.9.0-2
2011-11-22 21:45:26 upgrade network-manager 0.9.0-2 0.9.2.0-1
2011-11-22 21:47:31 configure network-manager 0.9.2.0-1 <none>
2011-11-22 21:47:31 status installed network-manager 0.9.2.0-1

And the empty resolv.conf:

eckert:~# ls -l /etc/resolv.conf
-rw-r--r-- 1 root root 30 Nov 22 21:47 /etc/resolv.conf
eckert:~# 

It seems like to problem occured at the time of upgrade from 0.9.0-2
to 0.9.2.0-1 .

 MB> Could you do the following steps:

 MB> 1/ stop network-manager (service network-manager stop)
 MB> 2/ restart ifupdown (service networking restart)
 MB> 3/ check if /etc/resolv.conf is corretly set

Yes it is OK, not modified from my manual configuration.
However, eth0 is down after this, and I got this:

eckert:~# service networking restart
Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces ... (warning).
Reconfiguring network interfaces...done.
eckert:~# 

 MB> 4/ start network-manager: NetworkManager --no-daemon --log-level=debug
 MB> (redirect the output to a file)
 MB> 5/ check if /etc/resolf.conf has been overwritten

No, it has not. And eth0 is down.

 MB> 6/ stop network-manager
 MB> 7/ check /etc/resolv.conf has been overwritten

No, still not overwritten.

I also tested with 'ifup eth0' before running NetworkManager in
debug-mode. The attached log-file is from the test with eth0
up. However, /etc/resolv.conf was never overwritten.

 MB> Attach the log file, the contents of /etc/network/interfaces and the
 MB> output of nm-tool to the bug report, please.

OK, attachments follows.
