Note that imputil is undocumented in 2.5, deprecated in 2.6 and  
definitively gone in 3.0

Yes, seems to be a bug. But given the current status of imputil, it's not  
likely to be fixed; certainly not in 2.5 which only gets security fixes  

I cannot test it at this moment, but I'd use the unicode item directly  
(that is, self.fs_imp.import_from_dir(item, name)). Or perhaps  
item.encode(sys.getdefaultfilesystemencoding()). str(item) definitively  
won't work with directory names containing non-ascii characters.

Why are you using imputil in the first place?
