Re: Python-Fu doesn't seem to work.

Dirk,

Thanks for letting us know about the Python bug. We haven't heard from
any Python users in a long time. 

The code hasn't changed. I suppose that something changed in Python or
gcc, Unless someone with embedded Python expertise/interest wants to
volunteer, we have nobody to work on this plug-in.
