Bug#889907: mate-session-manager: mate-wm does not work if $WINDOW_MANAGER is not set

[Denis Dordoigne]

Package: mate-session-manager
Version: 1.18.2-1
Severity: important

Dear Maintainer,

The mate-wm script try to get the name of the window manager using "gsettings get". "gsettings get" give the value between quotes, and the mate-wm script does not remove them before executing it : the command cannot be found.

If you want to reproduce the bug, run "unset WINDOW_MANAGER && mate-wm" :

****************
denis at kamoulux:~$ unset WINDOW_MANAGER 
denis at kamoulux:~$ gsettings get org.mate.session.required-components windowmanager
'marco'
denis at kamoulux:~$ bash -x /usr/bin/mate-wm 
+ SMID=
+ DEFWM=
+ GET=
+ '[' -z '' ']'
++ gsettings get org.mate.session.required-components windowmanager
+ WINDOW_MANAGER=''\''marco'\'''
+ '[' 'x'\''marco'\''' = xcompiz -o x = xcompiz ']'
+ '[' 'x'\''marco'\''' = xmate-wm ']'
+ '[' -z ''\''marco'\''' ']'
+ '[' -z ''\''marco'\''' ']'
+ OPT1=
+ OPT2=
+ OPT3=
+ OPT4=
+ '[' '!' -z '' ']'
+ case `basename $WINDOW_MANAGER` in
++ basename ''\''marco'\'''
+ exec ''\''marco'\'''
/usr/bin/mate-wm: line 159: exec: 'marco': not found
