That's unfortunate.

Can you reproduce this problem using a stock Subversion client?
Is your working copy on local disk?

That's not true. There are transactional safeguards in sqlite.
The details are documented at

I don't remember ever seeing this error message.

I would assume it's a problem with Cornerstone. Maybe it's some patch
they're applying to Subversion. I would try talking to them before talking
to this community. We're entirely unable to support Cornerstone software
since the software is closed source.

Since you're on Mac, does this database contain paths with non-ASCII
characters? There are known problems with this where MacOS X and Linux
or Windows SVN clients are used together with such paths. This might
not be related to the problem but it is still an interesting data point.
