Ignored signals, such as SIGPIPE in Mutt, are inherited by child processes. This can cause incorrect behavior in filter-like programs that expect SIGPIPE to be the default value of "Term". A couple other places in Mutt already reset SIGTERM, SIGTSTP, and SIGCONT, with a comment mentioning it really wasn't necessary. Since I don't much like messing with signals, I'll leave those resets in. Extract those plus SIGPIPE into a new function, mutt_reset_child_signals() and add that before each exec call. Thanks to Vincent Lefèvre for reporting the issue and for the initial patch, which this commit is based upon.
