I'm getting this traceback from time to time, in a kind of random,
unpredictable fashion (at least for me):
Traceback (most recent call last):

Sometimes this is accompanied of this other traceback:

TypeError: can only concatenate list (not "NoneType") to list
This is happening to me from some time now, I don't remember exactly
since when.
All these tracebacks seem to imply that monitor communication channels
are somehow shutdown, which breaks code completion. But how this can
happen and be fixed?
Cheers,
Carlos
