Bug 579782 – mail-client/mutt-1.6.0-r1 - Infinite loop when binding function keys to `help' in index

• Product: Gentoo Linux
• Status: RESOLVED UPSTREAM

gdb trace and muttdebug

Binding a function key to the `help' command in index context (for example "bind index <F1> help") will cause mutt to enter an infinite loop upon pressing "i" in the index view. I do not use a custom macro/bind for "i" in that case.

I can only reproduce this with the build on Gentoo, upstream mutt (both 1.6.0 and current hg HEAD) do not show this issue. I assume that some patch is the culprit.

Find attached the gdb trace and muttdebug0 output.

My USE-flags for mutt: 
"berkdb crypt gdbm gpg imap nls sasl smime smtp ssl tokyocabinet"

my first suspicion would be sidebar, but needs testing.
