Tramp problem with files under version control (subversion)

Tramp problem with files under version control (subversion)

Hello,

GNU Emacs 23.3.1 (Aquamacs)
Tramp-Version 2.1.20

accessing files on remote Linux systems works beautifully for me (thanks for the excellent tramp package!) - including handling of all version control-related issues (subversion). I have a near identical setup on a Solaris 10 box but here we experience problems under certain conditions: the problems are related to the login used with tramp and apparently have to do with version control (subversion). If I connect to the machine via tramp and start in a directory which does not contain files under version control, everything works fine. If, however, I encounter a directory that does, dired will show a listing but accessing files through dired will result in "Couldn't find exit status of `test -e somefile'", Tab-completion in the mini-buffer works, though. Opening a file via minibuffer will work (eventually) but display half a buffer of error message ending with "does not return a valid Lisp expression", these error messages vanish later. Maybe this is interesting: if I connect via tramp as a user who only has read-permissions for the files under version control, Emacs will (correctly) tell me "note: file is write protected" - but tramp works flawlessly. Both user configuration have a nearly identical .bash_profile which contains "export PS1="\h:\W> ", subversion works fine when used on the command line.

Re-running the session with
(setq tramp-debug-buffer t)
(setq tramp-verbose 10)
yields:

tramp.el has a lot of comments and workarounds for Solaris related
problems. 

Please look in tramp.el for "SunOS 5.11" and change it to
"SunOS 5.10". If the problem goes away, we might apply a weaker check at
this place.

Best regards, Michael.
