bug#17462: 24.3.50; bbdb-split: Invalid regexp: "Unmatched [ or [^"

[Sebastien Vauban]

Hello,

When receiving emails with Gnus, they're automatically sent to the right
folder thanks to BBDB. That works for years.

Reading them within Gnus works for years too, though today I have
apparently received an email that blocks the access to my "family-new"
folder.

See http://screencast.com/t/0xCWvhVjj.

The net impact is that I can't open that "family-new" folder anymore...

  ^^^^^^^^^^
bbdb-split is not part of Emacs, so why do you think this is an Emacs
problem?

In any case, a Lisp backtrace would be nice.

I oversaw the fact BBDB wasn't in Emacs, sorry.

IIUC, the sender has put a [ in my display name, and there is no
protection against such when matching regexps.

The error happens while running `gnus-user-format-function-r' - that one
is defined in your settings, right?  BTW, the arguments of bbdb-split
look like they are in the wrong order.

Probably some code should use regexp-quote, but doesn't.

I'm going to close this because I don't think there is any bug in Emacs
here; but feel free to keep discussing it here if you like.
