   Hi!

   Thanks for the reply.

   Unfortunately I missed a 'not'. I'm not able to reproduce it locally :(

   The corrupted .pyc file experience: I suppose that effect the behaviour
   both if the .pyc file is the main file or as an something that gets
   imported.

   :) T

     Perfectly good place to ask. Since you can replicate the problem, can
     you post the code that will trigger this? There are a few
     possibilities. I've once (not "once in a <time period>", once) seen a
     Python installation with corruption in a .pyc file, which resulted in
     really bizarre errors; but more likely, it's something that can be
     shown on multiple systems.

     It's definitely possible that threading can (a) introduce errors, or
     (b) move errors around and make them less obvious. Try to cut your
     example down as much as it can, but it wouldn't surprise me if
     threading remains in it.
