Package: xfce4-session
Version: 4.12.1-3
Severity: normal
Dear Maintainer,
Since a few days, my testing system (updated almost daily) issues a strange behaviour in starting the XFCE4 desktop :
the window manager isn't started, and the top most panel doesn't start, whereas another panel and some apps started at session start appear.
Restarting X eventually works again corrctly (lightdm + xfce4).
Here's an excerpt of .xsession-errors when that happend :
