CalledProcessError in Qubes VM Manager

[hansWURSCHT10000]

I'm on Qubes R3.0 and I think I got this error now for the third time. Always when my PC boots and as soon as Qubes VM Manager starts.

It says:

Whoops. A critical error has occured. This is most likely a bug in Qubes Manager

CalledProcessError: Command '['/usr/bin/wmctrl', '-R', 'Qubes VM Manager']' returned non-zero exit status 1 at line 542 of file subprocess.py.

Details:

----

----

I don't know why this error occurred.

I'm having the same issue in 3.2r1. It only started after an update to dom0 (update in the last week).

I have the same problem on R3.2.
I didn't change anything to the system. Yesterday it was working without problems, but today i have the above error message, and no windows borders.

I tried to kill the qubes manager process and relauch it : the message does not appear anymore, but when i restart the computer, it reappears.

So i tried to update dom0, nothing changed.

How to recover an operational system?

Ok
I reproduced the bug on a R3.2 freshly installed:

1. create some windows (e.g. Firefox of sys-net)
2. press ALT+F4 multiple times (this will close all the windows and when all are closed, the xfce session menu opens.
3. click the shut down button
4. power on and login

Now all the windows borders disappeared, there is only 1 desktop instead of 4 and an error prompt says: CalledProcessError: Command '['/usr/bin/wmctrl', '-R', 'Qubes VM Manager']...

Thanks to this post, i followed the instructions of http://wiki.xfce.org/faq#i_have_only_one_desktop_and_can_t_move_my_windows_anymore_help

So, to resolve the problem, press ALT+F2 and type the following command :

xfwm4 --sm-client-id=${SESSION_MANAGER##*/} & disown

Normally, all windows will reappear and no error message will prompt at startup.
