svn: Cannot replace a directory from within

Yesterday I was trying to do a merge in a svn repository using a command like:

rado@ubuntu-laptop:~/svn-wc/$svn merge svn:// svn://

just to get the really strange error – „svn: Cannot replace a directory from within“.

After reading through mailing lists messages, bug reports and anything else I could find about this error there was no enlightenment.

In the end the cause turned out to be a simple typo in one of my very/long/paths.

I shouldn’t trust error messages too much!
