[Zope] CorruptedTransactionError

[John Glossner]

I get the sinking feeling I'm in deep yogurt. 

Before getting this error, I was running Squishdot 0.3.2 (but I've
made edits so it is not a pure Squishdot). I have been happily
using 0.3.0 for a few days. This afternoon (with no know changes
made - but I won't swear to it), I was all of a sudden unable to
access my Squishdot site. I got KeyError (which is appended below
since it still happened to be cached in my browser). I could still
access other parts of my site.

Then, after looking around for what could have caused this,
I decided to try to restart Zope. Now I can not restart Zope
and it says my Data.fs is corrupt. My question is: Is there
anyway to fix this? Obviously, I can rename Data.fs and 
Zope will restart. However, I want to rescue everything I
can out of Data.fs.

Thanks,
John
