I now wanted to send a strace of that, and found some other strangeness:
The client side (doing a commit) hangs with
        write(4, "change-file-prop ( 4:c470 9:svn:" ..., 4096 <unfinished ...>
while the other side (svnserve, called by ssh) does

        08:58:12.865719 select(0, NULL, NULL, NULL, {0, 10000}) = 0 (Timeout)
        08:58:12.878338 select(0, NULL, NULL, NULL, {0, 10000}) = 0 (Timeout)
        08:58:12.888718 select(0, NULL, NULL, NULL, {0, 10000}) = 0 (Timeout)
        08:58:12.898829 select(0, NULL, NULL, NULL, {0, 10000}) = 0 (Timeout)
        08:58:12.908707 select(0, NULL, NULL, NULL, {0, 10000}) = 0 (Timeout)
        08:58:12.921092 select(0, NULL, NULL, NULL, {0, 10000}) = 0 (Timeout)
        08:58:12.930662 select(0, NULL, NULL, NULL, {0, 10000}) = 0 (Timeout)
        08:58:12.940865 select(0, NULL, NULL, NULL, {0, 10000}) = 0 (Timeout)
        08:58:12.950751 select(0, NULL, NULL, NULL, {0, 10000}) = 0 (Timeout)
        08:58:12.960672 select(0, NULL, NULL, NULL, {0, 10000}) = 0 (Timeout)
and so on, and so on ...
Any help?

Thank you!

Regards,

Phil
