Is there actually a directory (we have no folders in
UNIX/Linux filesystems) at the location indicated?

The trailing slash is not necessary to exclude a directory.

To make the temp files a template is created by prepending
dot and appending .XXXXXX, the XXXXXX is replaced by
simi-random chars by mkstemp or in the absence of mkstemp
tempfile.

If correctly built on a Linux box rsync will call mkstemp
followed by fchmod.  The only way you could get a invalid
arguments error without .XXXXXX at the end of the file name
would be if mkstemp succeeded but with preserve_perms
enabled fchmod failed which is nearly impossible in this
context.

If incorrectly built or on a some non-Linux platforms it
does a mktemp followed by do_open which could produce the
error condition you present.

Based on this i have to conclude that your binary was
incorrectly built.

I am curious though as to what is causing the problem.  It
would help tremendously if you could narrow it down to a
small test case that strace could be run on.

Also, try it to a native filesystem on a reliable interface.
In other words ext[23], reiserfs, jfs or xfs on IDE or SCSI;
no FAT, USB or firewire.
