svnsync Assertion failed: window->sview_len == 0 |...

In performing a svnsync the assertion below appears. I have not seen
this logged. Has anyone else run across it?

I have tried this several times and the assert happens every time at the
same point in the sync.

The last changed revision of the repository is 341.

This is using Subversion 1.5.0 from CollabNet on Windows XP Professional
service pack 2

Thanks!
