Subject: liboobs sends invalid messages to system-tools-backends

Date: Tue, 16 Sep 2014 11:16:45 +0400

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:

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.

[Message part 1 (text/plain, inline)]

reassign 761806 system-tools-backends 2.10.2-1
retitle 761806 system-tools-backends: patch - fix current user's info retrieval
tags 761806 patch
thanks


Whoops...

The further investigation showed that the bug is not in liboobs, but a level below -
in system-tools-backends. Therefore I'm reassigning this bug report there.

Also I've managed to fix this very bug, so I'm attaching the debdiff with the fix for
system-tools-backends.


Hope to see it accepted soon. Thanks in advance.
