Your .svn/tmp directory may be missing or corrupt; run 'svn cleanup' and try again

I am not sure what this issue is all about. Is it because of the long file
names? I can check out the directory via Tortoise but not on command line.

I am using TSVN version 1.5.3 and Collabnet's command line client version
1.5.2 on Windows.

Any ideas?

Thanks. A.
