I think I have that same problem. When I generate my projects
that I use Subversion with, the .svn folder in each directory is
still there, but when I try to commit, it throws an error and says
it can't find a file in the "tmp" folder. My workaround to this
point has been to copy any changed files to another location,
delete my output folder, update to get the last version, and put
the updated files in. That's the only way I've found that
Subversion will accept my changes.
I just googled to find more on this topic, and the only thing
on this problem I found was this page:

The solution, the reply says, is to generate your project to
a folder that is not under version control, which means you have to
copy the output and paste it into your version-controlled
directory, then commit to the repository. Fun. A little simpler
than what I've been doing, at least...
