bug#29074: 26.0; Cannot sent bug report in Emacs 26 pretest

[Drew Adams]

I was in buffer *Backtrace* and did M-x report-emacs-bug.

I entered bug-report text and hit C-c C-c, then answered "yes".  My
*unsent mail to bug-gnu-emacs* buffer was killed and a dialog box was
displayed by MS Outlook, which said, "The command line argument is not
valid. Verify the switch you are using".

I tried again, and Emacs said that I already sent the message (which is
not true) and asked if I wanted to send it again. I answered yes. Same
thing.

I tried again, after closing Outlook altogether.

This time I got the error message "Cannot start Microsoft Outlook. The command line argument is not valid. Verify the switch you are using."

Attached are the two error messages.

It seems that using a mail client from `M-x report-emacs-bug'
is broken for the pretest.  But sometimes I have been able
to send bug reports from it, I think.

I couldn't reproduce this.  I tried on 2 different Windows 7 systems,
and it worked as expected for me, both when Outlook was already
running and when it wasn't.

Does this happen in "emacs -Q"?  If it does, then please step in
Edebug through mailclient-send-it, which is the function emacsbug.el
invokes in this case, and tell what are the arguments with which it
calls browse-url.

If it doesn't happen in "emacs -Q", then please try to see what gets
in the way.  Is mailclient-send-it at all called, and if it is, how
does it call browse-url?

Also, what version of Outlook/Office do you have on that system?

A misconfigured system mailto handler is not an Emacs issue.

For the record: that old article from MS Support is not relevant to
the issue at hand, because the default setting for handling the
'mailto' URLs was fixed on Windows years ago, and is out of the box
exactly like this article says.

The reason for the failure is most likely quoted strings "..." in the
Subject of the report.  This should be fixed in Emacs 26.1 and later.

I haven't seen it again, and I think I've filed other Emacs 26 pretest
bugs since then.  I believe I ran into it from emacs -Q, but I'm not
100% sure of that.

I now have Outlook/Office 2016.  I "upgraded" to it recently from 2007.
The version we have may be tweaked by my company, to integrate it
with the mail server etc.  Not sure what that "integration" might involve.

If the problem occurs again I'll try to track down more info about it.
