I tracked the problem down to the regexp search, which probably attempts to match a very big piece of text (several lines). I changed the regexp to only match a single line. The result is probably slower, but doesn't produce the error. --- emacs/notmuch-wash.el | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/emacs/notmuch-wash.el b/emacs/notmuch-wash.el index 26a3f88..051dd17 100644 --- a/emacs/notmuch-wash.el +++ b/emacs/notmuch-wash.el @@ -218,7 +218,7 @@ Perform four transformations on the message body: ;; Insert a blank line before a citation if there isn't one.
