Greetings,

After xpra attach is called, a number of Python error messages is displayed,
suggesting that some modules xpra tries to import do not exist:

peterp@bach:~$ xpra attach ssh:handel:100
xpra client version 0.10.11

2014-01-10 00:10:31,757 Attached to ssh:handel:100 (press Control-C to detach)

The functionality does not seem to be affected but these error messages are
still somewhat disconcerting.

Thank you!

Best regards,
Peter

Dear Peter,

Those are just harmless warnings that are safe to ignore. There is
nothing we can do about them but you might find interesting to read
the following corresponding bugs:
