Internal database error

[Rick Barter]

In trying to "save a copy" of manila.websites.root I get the message:
  "Internal database error: attempted to read a free block. Try to  
save a copy and relaunch with the new database".

That error message dialog box will not go away leaving a restart of  
Manila the only way.

If I go back several days to a backup, I get the same error message.

I find that I can't even get to the site causing the problem to  
uninstall it without the error message coming up and causing me to be  
stymied with a restart the only option.

Any suggestions? i'd be happy if there was a way to simply delete the  
problem site.

Thanks
