I haven't met that, but K-9 does a couple of annoying (to me) things with drafts.
First, it creates a new draft each time I switch. No content is lost, but having a couple of drafts of the same email is annoying. Especially if I'm not paying attention or just rushing; very easy to pick the wrong draft!
Second, it doesn't remove any of the drafts after I finish and send the email. So I have to delete them manually or they just accumulate.
