First CVS command generates empty buffer

[Marshall, Simon]

I get this every time with a working copy of a file from a local CVS
repository, but not with an emacs file from the savannah repository.  My cvs
is 1.11.5.

CVSROOT=$PWD/cvs        # create a local CVS repository if you don't have
one
cvs init
mkdir foo
touch foo/bar
cd foo
cvs import -msnafu foo bar fubar
cd ..
cvs checkout -d bar foo
.../src/emacs -Q
C-x C-f bar/bar # for me, any file under a local CVS repository 

At this point, *Messages* contains:

For information about the GNU Project and its goals, type C-h C-p.
Note: file is write protected
Loading vc-cvs...done

Now do C-x v l, and the window splits with bar at the top and a window
showing *vc-change-log* at the bottom.  BUG: The *vc-change-log* buffer is
empty (and its window is 3 lines high).

At this point, *Messages* contains:

For information about the GNU Project and its goals, type C-h C-p.
Note: file is write protected
Loading vc-cvs...done
Loading vc...
Loading easymenu...done
Loading vc...done
Running cvs in the background...
Loading log-view...
Loading easy-mmode...done
Loading log-view...done

Interestingly, if I C-x o C-x v l, then *vc-change-log* is correctly
generated (though its window is still 3 lines high).  *Messages* now
contains:

For information about the GNU Project and its goals, type C-h C-p.
Note: file is write protected
Loading vc-cvs...done
Loading vc...
Loading easymenu...done
Loading vc...done
Running cvs in the background...
Loading log-view...
Loading easy-mmode...done
Loading log-view...done
Running cvs in the background... done

Note this time I get a " done".

Note also that this is not specific to C-x v l.  Checkin a change to bar,
then:

.../src/emacs -Q bar/bar
C-u C-x v = RET RET RET         # diff between previous 2 revisions

I get a 3 line high *vc-diff* window where the buffer contains "No
differences found."  Repeating the above command in bar will generate the
correct diff, and *Messages* gets a message with " done" as above.
