usually do not have translators to read other languages for them.

When I run the CVS version of emacs inside a Clearcase Vob, emacs stalls
right after the start with the following message:
error in process filter: Wrong type argument: stringp, nil

Since this only happens in a clearcase Vob, I figured it should have something
to do with clearcase.el or the packages clearcase.el is using.

I'm using Kevin Esler's clearcase.el and this runs just fine in emacs 21.3.
clearcase.el uses the package tq.el and there's one change in tq.el (aside
from a few comments) that seems to cause it, i.e. the change to
set-process-filter in tq-create:

from:
    (set-process-filter process
                        (`(lambda (proc string)
                           (tq-filter '(, tq) string))))

to:
    (set-process-filter process
                        `(lambda (proc string)
                           (tq-filter '(, tq) string)))

When I change it back to the 21.3 version, it works fine.

Does anybody know why that was changed? If this change is necessary then
I guess the packages using tq.el (like e.g. clearcase.el) need some adaption.

There's one more thing that worries me, that I can't interrupt emacs when
this error happens.

Appreciate any help and hints.

Klaus
