possible incompatibility in 3.1 with 3.0.6

[Carlos Carvalho]

Got this strange error:

receiving incremental file list
rsync: opendir "/.~tmp~" (in <sender-module>) failed: Permission denied (13)
IO error encountered -- skipping file deletion
rsync: opendir "/path/.~tmp~" (in <sender-module>) failed: Permission denied (13)
invalid multi-message 22:4 [sender/inc]
***************************************
rsync: connection unexpectedly closed (34741 bytes received so far) [receiver]

What I find strange is the "invalid multi-message" line. The
origin/sender is 3.1 HEAD-20091127-0430GMT and the receiver is 3.0.6
(which produced the above log). Is it an incompatibility? It *seems*
to happen only when there are permission denied cases.

Anyway, the receiver shouldn't have aborted.
