Vcs: SVN: Can't checkout project on OSX

Steps to reproduce:

• have a local svn repository at hand
• start QC and go to 'New File or Project...' -> 'Import Project' -> 'Subversion Checkout'
• enter the local repository URL and a destination directory

Current result:

• checkout seems to be successful, but a split of a second I'm getting an error
  Output on OSX:

  Executing in /tmp: /usr/bin/svn checkout file:///Users/stenger/tmp/svn123 svn123 --non-interactive file:///Users/stenger/tmp/svn123 svn123
  svn: E125002: 'svn123' does not appear to be a URL
  

Note: This works fine using Linux. But it looks like the generated command differs for both platforms.
Output on Linux:

Executing in /tmp: /usr/bin/svn checkout --non-interactive file:///home/chris/tmp/myTestSVN myTestSVN
