Are you absolutely sure your running 0.6.0-rc4. This issue looks like a duplicate of issue #202 which was fixed by commit 274b7e7 in 0.6.0-rc4. This bug did exist in 0.6.0-rc3. Please double check your running 0.6.0-rc4 or newer.

sorry you are right, this was rc3, i have tested it with clean rc4 and it works fine
