Package: tvtime
Version: 1.0.2-7
Severity: important

When [1] is enabled, tvtime no longer starts and the following
message is printed instead:
Starte tvtime 1.0.2.
Lese Konfiguration aus /etc/tvtime/tvtime.xml
Lese Konfiguration aus /home/helge/.tvtime/tvtime.xml
xcommon: No window manager name property found (WM not compliant).
Get=C3=B6tet

or roughly translated back to English:
Starting tvtime 1.0.2.
reading configuration from /etc/tvtime/tvtime.xml
reading configuration from /home/helge/.tvtime/tvtime.xml
xcommon: No window manager name property found (WM not compliant).
Killed

In the syslog I see the following messages:

When recompiling the kernel without [1] then tvtime works again. (The
xcommon line appears nevertheless, seems to be harmless).
