Errors reading an MH mail message when auto-fill is turned on

Running XEmacs thusly xemacs -vanilla -eval "(add-hook 'text-mode-hook 'turn-on-auto-fill)" produces this error Signaling: (end-of-buffer) fill-region-as-paragraph(3809 4025 left nosqueeze) fill-region(3809 4025 left nosqueeze) fill-flowed() mm-inline-text((#<buffer " *mm*"> ("text/plain" (charset .

(I have kept about a dozen of these messages.) I am using MH-E 7.1, but it also occurred with MH-E 7.0 (and possibly before). I'm appending just one message that gives me an error, and the output of `describe-installation' and `mh-version'. --- Vladimir P.S. I'm sending this message to both xemacs-beta and to mh-e-users because I don't know where the problem lies, but I only get these kind of errors when using MH-E. ------------------------------------------------------------------------ Vladimir G.
