Package: liboobs-1-5
Version: 3.0.0-1
Severity: important
Hi,
I'm running Debian Testing, all packages are up-to-date.
When I run users-admin (from gnome-system-tools package) from the
terminal, it shows the following error:
(users-admin:1146): Liboobs-WARNING **: There was an unknown error
communicating asynchronously with the backends: Launch helper exited
with unknown return code 255
If I try to change the full name of my user account, it fails [*]
with an error again:
(users-admin:1146): Liboobs-WARNING **: There was an unknown error
communicating with the backends: Launch helper exited with unknown
return code 255
When I look in /var/log/syslog after that, there are some error
messages as well.
1) after users-admin starts:

2) after I change the full name and press the button to apply the changes:

So it looks like liboobs sends a malformed message (with invalid
interface name) to the backend.
[*] Though the GUI will show that the full name has changed, after
restarting users-admin you'll see that it actually didn't. This is
due to another bug in liboobs, not related to this one.
