Severity: grave

Dear maintainer

I use Debian Jessie with the MATE desktop environment.

The application for adding and removing users and groups (command: 
mate-users-admin) will not start any more when clicking:

System > Management > Users and groups

System log:
Oct 11 13:51:30 desktop-computer kernel: [ 1141.192153] traps: 
mate-users-admi[2865] trap int3 ip:7f982286b261 sp:7ffda2bb4830 error:0
Oct 11 13:51:30 desktop-computer kernel: [ 1141.192157] in 
libglib-2.0.so.0.5000.3[7f982281b000+112000]

When using a terminal window:
root at desktop-computer:/home/maarten# mate-users-admin

(mate-users-admin:5553): Gtk-ERROR **: GTK+ 2.x symbols detected. Using 
GTK+ 2.x and GTK+ 3 in the same process is not supported
Traceer/breekpunt-instructie
root at desktop-computer:/home/maarten#

I did not have this problem earlier. I do not have any broken packages 
and debsums -as indicated that all my packages are intact.

Synaptic (package manager) tells that mate-system-tools also contains 
the tool for adjusting the date and time, and the tool for setting the 
network options. These two tools were found easily in the Configuration 
Centre. However, those tools also do not start any more.

Debian Jessie is being advised for production machines. I hope that this 
programming error gets corrected soon.

With kind regards

Maarten
