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...
