Hello Christian!
(Sorry, I only just spotted this - you forgot to copy me in to your
emails and I'm not subscribed to this bug report.)
Here's the result of running it with --debug:
erdos:~ # backintime backup --debug
DEBUG: [common/backintime.py:668 argParse] Argument(s) used: {'debug': True,

and then it continues normally.
Further data:
I can run "backintime backup" in a terminal via ssh (with the -X
option) as a regular user; this environment contains the variable
DISPLAY=localhost:12.0. After su'ing to root, if I then export
DISPLAY=localhost:12.0 as root, "backintime backup" works fine. So it
does seem to be related to this DISPLAY setting. However, if I ssh to
the machine without using -X, so DISPLAY is unset, and try running
"backintime backup" as this regular user, it works fine too. So there
appears to be some subtle combination of DISPLAY and running as root
going on.
Best wishes,
Julian
