rsync fails with 2 sources

[Andreas Ley]

Hi!

I seem to have a similar problem. I checked different versions and options,
and it seems to happen when the server version is >= 2.6.1 - there's no
problem with 2.6.0. The client version doesn't matter. The --delete option
is required to show the bug. The two directories may well be uptodate and
even empty. It doesn't work with any two directories though. And I get a
SEGFAULT.

Listing on the client:

mail2:~# ll -d / /usr /usr/local;ll -aR /usr/local/lib/ /usr/local/etc/
drwxr-xr-x   22 root     root         4096 May 14 16:13 /

Listing on the server:

The two machines are Debian stable with kernel 2.4.26.

Hope this helps finding the bug. Can I provide more information or run more
tests?
