This is actually coming from ipython, not matplotlib. This indicates that version of ipython you have installed was written for an earlier version of wxPython. It may still work despite this warning. (Maybe an ipython expert can comment on that.) The current release of ipython (0.8.1) has been updated and does not present this warning with the current release of wxPython (2.8.4.0). If both your ipython and wxPython are from official Fedora packages, that's a version mismatch, and should probably be reported as a packaging bug to Fedora. You may want to upgrade ipython if you can do so easily. > Then I threw a test command to ipython and things seem to be wrong > again.

AFAIK, IPP is "Internet Printing Protocol", and this message usually comes from CUPS or something. My best guess is that when wxPython initializes its first window, it also initializes the wxWidgets printing stuff, and there's something underlying that that is broken on your system. (Only a guess). Again, it's possible that things could continue normally despite this warning. I would look into your printer configuration to see if these messages can be eliminated. > The correct figure was generated in a GUI but error messages pop > up whenever "plot" is used.
