You're right, in the beginning I didn't realise that one shouldn't mix the 
two sources, then I read about it and tried to clean up and go with Debian 
packages only, but apparently I didn't quite manage that :-/ Now I removed 
all ROS packages and re-installed them completely from Debian only. And 
still running "rosrun tf2_tools ..." produces the same error :-( I can now 
run view_frames.py stand-alone, but so far it hasn't produced any 
output... I'll try some tf2 demo to see, if the reason is in my wrong TF2 
use or in the setup / in packages.

Thanks
