Hello,
When upgrading the last cython, it seems that loading the lexicon
pickle failed. I think I had an incompatible version around
somewhere. Anyway, the error I got was this:
Compiling module Cython.Plex.Scanners ...
ERROR: ('__init__() takes at least 2 arguments (1 given)', <class
'Cython.Plex.Lexicons.Lexicon'>, ())
Extension module compilation failed, using plain Python implementation
running install
The error occurred while unpickling the lexicon. Under this condition,
it seemed like a good idea to just regenerate the pickle file if
there's an error loading it. This is what the following patch does:

Made lexicon unpickling more robust; on error it regenerates it.
