rmail-get-attr-names: Corrupt attribute header in message

rmail-get-attr-names: Corrupt attribute header in message

[Kenichi Handa]

With today's update, I frequenty get the above error in
rmail, and RMAIL buffer is left swapped (i.e. showing the
RMAIL file itself).

This is an example of the header of such message.

Well, that sounds like it might be a bug.

What does the next line look like? Does it start with whitespace?

What does (rmail-get-header rmail-attribute-header) return for this
message?

The next line is empty.

"-------"

I'll attach the small RMAIL file that causes this problem.

That should have 8 elements, not 7.

There are three messages in the attached file.
In the second and third one, the X-RMAIL-ATTRIBUTES header is indeed
corrupt. It only contains 7 "-" when it should contain 8. If you add
an extra "-", it should work.

I don't know why that happened; it should not. Perhaps you could look
into how it came about?

Such headers are wrong, but I'll change it to just print a warning
rather than giving an error in such cases.

Hasn't the number of attributes been increased after pmail
was merged to rmail?  I think the number was 7 when my RMAIL
file was converted to the mbox.

How about just silently adding one more "-" in such a case?
