[Moin-user] 1.8.4/1.8.8 crash on save

[Peter Olsen]

I keep getting the following error whenever I try to save a page in  
either Moin 1.8.4 and 1.8.8.
I was running 1.8.4 without trouble when I started getting a  
persistent CacheError.  I ran cleancache and now I'm getting these  
errors.  Preview works but I can't save.  Can anyone suggest a fix?  I  
want to upgrade, but I don't want to do so until my current wiki is  
running correctly.
