Right, the IEP interpreter sets sys.argv to [], while it should have set it
to ['']. (I used the standard Python shell as an example and must have
misread it). I will fix this bug right now.

In the mean time, you can put "sys.argv = ['']" somewhere before importing
matplotlib, or better yet, put that code in your PYTHONSTARTUP file. Another
option is to run your code as a script, which sets the first element in
sys.argv to the scripts path.

Thanks for reporting this!
