Hi Chris,

This bug is now solved. Try to download and replace the following file
inside vortex code [1] you are using. The patch is now integrated into
the SVN and will be released in the next stable version.

The bug was caused by a not proper detection of a previous internal
fragmented frame, due to a wrong check, which fails if the first octet
of the previous frame fragment received has a binary value equal to 0.

The reason that was causing regression test to not detect this issue is
that local connections never gets fragmented or delayed, making the
internal fragmentation code to be never activated until the test is done
using two different computers.

Let me know if this solve the issue,

Thanks for reporting, Cheers!
