I cannot reproduce this here.  I tried on 2 different networks with 4
different machines, and couldn't reproduce the crash, both when a
shared directory is mapped to a drive letter and when using UNCs.  I
see the expected behavior: I can visit files in the shared remote
directory, and if the directory's sharing permissions allow only
read-only access, I get an error message when I try updating files in
it.

Does this happen in "emacs -Q"?  If not, please try to identify which
of your customizations could be related (i.e. if removed from .emacs,
the crashes disappear).

If the problem persists in "emacs -Q", perhaps you left out some
crucial detail of the recipe to reproduce the problem.  Please
describe the recipe in more detail, including how exactly you make a
directory shared, what permissions you define for its access, etc.

Alternatively, if you or someone else who reads this can reproduce the
problem under a debugger and send a backtrace, we could perhaps cut to
the chase much faster.  (If you want to give this a try, you will
probably need a development snapshot, because I believe the official
releases have their binaries stripped, so a debugger will give no
useful information.)

Thanks.
