Subject: 23.0.60; Rmail mode totally broken
Date: Fri, 23 Jan 2009 10:05:26 +0000

This morning after updating from the CVS I cannot read any RMAIL file

File mode specification error: (wrong-type-argument stringp nil)

I am seeing messages about writing to /tmp/rmailXXX that I have not
seen before.  This happens on a number of RMAIL files I have, large or
small.

I managed to capture a backtrace

Not sure why it is converting from babyl format anyway, but it is
getting it wrong!

I haven't been able to reproduce this bug.

Could you visit lisp/mail/rmail.el, evaluate the buffer, then trigger
the Lisp backtrace again?  This will give a more informative backtrace.

Thanks.

Ah, I can reproduce it now.  I've checked a fix into CVS.

We just switched rmail to the new rmail-mbox code, which stores RMAIL
files in mbox format, rather than babyl.

loaded a small RMAIL file and as it did not display labels I thought I
would try the headers (command h)

Debugger entered--Lisp error: (search-failed ",,")
  search-forward(",,")
  rmail-make-summary-line-1(1)
  rmail-make-summary-line(1)
  rmail-new-summary("All" (rmail-summary) nil)
  rmail-summary()
  call-interactively(rmail-summary nil nil)

So that makes rmail unusable for my world.  I have 18000 messages in
one file and keywords and header is important

I just fixed a couple of bugs in the label handling.  I do see labels
displayed on the mode-line, and the functionality explained in the
section on Labels in the manual now seems to work fine.

What is the nature of this mail-handling code of yours?  Do they make
use of internal Rmail functions, and, if so, what functions are these?

Closing this because the specific issue has been addressed. If
necessary, please open new bug(s) with concise, complete descriptions
of any remaining rmail issues.
