[Zope] unknown IndexError 41

[Peace&Love]

hello!

everything was working fine until a couple of days ago and now..
Obviously I have no exact traceback of what was done on the machine, but I 
updated my gentoo box by emerging some apps (nothing apparently involving 
plone/zope/python/mysql...)  :-(

Now I really do not know where to bang my head..perhaps on re module??

thanks..
Stefano.


when I call the external method zope returns this weird 'error 41':

...
IndexError
