python plugin: Incorrect Function Description.

[Nils Kanning <nils kanning de>]

The descriptions of python functions do not show up correctly in the
"Function Selector". Only "Incorrect Function Description." (gnumeric
1.6.3, debian unstable) or "?" (gnumeric 1.7.7, experimental) is
displayed.

This happens with own functions and with the functions defined
in /gnumeric/plugins/py-func/py_func.py.

Any ideas how the descriptions are defined right?

Thanks
Nils
