while working on recreating bug 380598, I noticed that removing a tag from a local message wasn't actually removing it from the x-mozilla-keys header. I'd defined a bunch of tags in my profile, as part of bug 380598, which had partly to do with the problem. Fix upcoming.

ugh, this code is truly horrible, but until it can be rewritten, this should fix the problem I was seeing. Basically, as we're iterating over the key headers in the mail message, to find the keys we want to add/remove, we need to reset the line buffer each time we seek back to the start of the message.

Comment on attachment 325031 [details] [diff] [review] proposed fix I wonder why there isn't an API for that. Or maybe linebuffers suck and we need a new API ;-)

linebuffers seem pretty barebones...
