0.51 bug: gnus-article-read-summary-keys is called with nil argument

[Vladimir Volovich]

Hi,

When i pasted the following text with buttons from a message to the
mail composition buffer, i got an error:

Signaling: (wrong-type-argument stringp nil)
  gnus-article-read-summary-keys(nil)
* call-interactively(gnus-article-read-summary-keys)

when moved a cursor inside the pasted text and trying to edit it
(e.g. put the cursor at the beginning of line [12. image/jpeg] and
press backspace). Also, the behavior os some keys became strange
(cursor was moving without a reason in the beginning of buffer, some
random text was pasted, etc).

[1. image/jpeg]...

[2. text/plain]

3.  [ ] text/plain          [ ] text/plain          [*] multipart/mixed     

[12. image/jpeg]...

[4. text/plain]

	Best regards, -- Vladimir.

It is because the pasted texts still keep button properties. This
error also happens when press 'q' in article buffer if summary buffer
is killed.  I guess, gnus can do nothing other than ignoring. Ignoring
may confuse you, when you press backspace but nothing happens.

I've now made all (well) the text-prop keymap commands beep a better
error message when invoked outside of the article buffer.

Pressing `delete' inside a pasted button moves the cursor at the
beginning of a buffer.

I don't think it's worth bothering to protect all the button
commands.
