ok, I see.

I am quite surprise about that (even somewhat disappointed). At least that 
requires thinking carefully if you are in a linked directory (somewhere in 
your path) when doing a link.

You are right yes. I was thinking that the shell knows the current path, e.g.

rd@silverboxy:~/tmp.nobackup$ mkdir a
rd@silverboxy:~/tmp.nobackup$ cd a
rd@silverboxy:~/tmp.nobackup/a$ mkdir b
rd@silverboxy:~/tmp.nobackup/a$ cd ..
rd@silverboxy:~/tmp.nobackup$ touch test.file
rd@silverboxy:~/tmp.nobackup$ ln -s a/b c
rd@silverboxy:~/tmp.nobackup$ cd c
rd@silverboxy:~/tmp.nobackup/c$ ls ../test.file
ls: ../test.file: Datei oder Verzeichnis nicht gefunden
rd@silverboxy:~/tmp.nobackup/c$ ls ../../test.file
../../test.file

If the shell would not be aware of the current path (symlinked), it could not 
do that correctly.

rd@silverboxy:~/tmp.nobackup/c$ cd ..
rd@silverboxy:~/tmp.nobackup$ ls test.file
test.file
rd@silverboxy:~/tmp.nobackup$ 

...well at least I learnt something here for me: use symlinks with care in 
future.

I am going to move my complete /usr to /mnt/hda1 and the mount it directly 
as /usr. That should make things working again.

Do you think it is worthwile to open a bug / wishlist report (where?) that 
epiphany dies not with a segfault, if a file is not there?

That was great support. Thank you very much.

Thanks,
Rainer
