I was trying to do a svn cleanup because I can\'t commit the changes in my working copy, and I got the following error:
sqllite: databas
After a power blackout, I ran into the database disk image is malformed error and the suggested reindex nodes command did not fix all issues due to violated constraints. Also the procedure described in http://mail-archives.apache.org/mod_mbox/subversion-users/201111.mbox/%3C874nybhpxi.fsf@stat.home.lan%3E did not resolve the problem.
Solution in my case:
This may be useful, if your original svn checkout contains many modified or unversioned files and you don't want to switch to a fresh svn checkout.
