emacs -Q
 
C-x d some-directory
 
M-x occur
 
In the occur buffer:
 
C-x C-q
Move cursor to a date field and hit `w'.
You get an error saying that the Dired buffer is read-only.
 
That's true, but it's not clear that this is the most helpful message at
this point.
 
Now kill the Dired buffer.  Then move the cursor to a date field in the
occur buffer and hit `w'.  You get this error, which is definitely not
the right error message here:
 
self-insert-command: Wrong type argument: stringp, nil

I cannot reproduce it as described.

Really?  Are you using the same build?
It's 100% reproducible here, with the build I cited, following the recipe I
described.

I forgot to mention that you must provide a pattern to `occur' that some file
names match, so the occur buffer is not empty.  Doing that, following the recipe
should give you the same behavior I reported.

What do _you_ see, when you insert a char in Occur after killing the Dired
buffer it was built from?  Try again, with the same build - I'm sure you'll see
what I described.

24.0.50? I've tried with the trunk, and with the 24.0.91 pretest.

Following your recipe, I don't see any error.

Yes. I supposed as much. I'm trying in the trunk workspace, and the
pattern is "a", so there's plenty of files.

C-h k says that "w is undefined", so typing w (or most characters) does nothing.

Where can I get that build?

Hm.  Did you toggle read-only, using C-x C-q?

Not sure what you did, but it should not be undefined.  After toggling
read-only, all such chars should be bound to `self-insert-command'.  (Whether
they call all actually insert is a different matter.)  Be sure you move to, say,
a date field of Dired - out of the read-only areas (e.g. linenos), in any case.

This is exactly what I did:

emacs -Q
C-x d <RET>   ; Default dir is C:\emacs\trunk
M-x occur <RET> a <RET>
C-x o      ; to go to the Occur buffer
C-x C-q
C-6 C-n   ; to go to the line containing .bzrignore
M-9 M-f   ; to go to the date
w            ; no effect
C-x k trunk <RET>
w            ; no effect

Am I doing it wrong?

Assuming you're talking about
http://alpha.gnu.org/gnu/emacs/windows/emacs-20111107-r106319-bin-i386.zip,
AFAICS, that's 24.0.91, not 24.0.50. In any case, I don't see any
problem with that binary either.

Sorry for the noise.  No, you were not doing it wrong, and there is no such bug
- I will close this.  Thanks for testing, in any case.

I apparently was using an old Emacs 24 binary (from September 05, I think).  Not
sure how that happened.
