I seem to remember having similar problems a long time ago and fixed them by re-ordering the configuration lines in .muttrc. I attributed it to Mutt corrupting its stack while processing .muttrc, but I really don't know. Good luck, I hope you get a better answer.
Perhaps you could try upgrading Mutt. I see 0.71-1 is available. -- -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] . Trouble? e-mail to [EMAIL PROTECTED] .
