Subclipse does not execute the ls command. It is possible that the
Subversion adapter we are using is doing something like that. It is not
our code so it is hard to say. From the stack trace it looks like you are
using JavaSVN. I would recommend you try JavaHL, this would mean getting
the Subversion binaries.

I think that JavaSVN suffers from a big performance hit on *nix in trying
to support and detect symlinks. I think there is a property you can set
to tell it to not do this checking and it will speed things up. I do not
know what that is. If you search the archives for javasvn and symlink you
can probably find it.
