invalid-function

With the latest released packages, and xemacs-21.4.10rc3, I now get this when I hit 'q' in gnus: Signaling: (invalid-function (macro . #<compiled-function (&optional n) "...(14)" [n delete-region (progn (beginning-of-line) (point)) progn forward-line 1 ((point))] 5>)) gnus-delete-line() nnheader-find-nov-line(3392) nnml-nov-delete-article("mail.spam" 3392) nnml-request-expire-articles((3383 3384 3385 3386 3387 3388 3389 3390 3391 3392 3393 3394 3395 3396 3397 3398 3399 3400 3401 3402 3403 3404 3405 3406 3407 3408 3409 3410 3411 3412 3413 3414 3415 3416 3417 3418 3419 3420 3421 3422 3423 3424 3425 3426 3427 3428 3429 3430 3431 3432 3433 ...)
