wrong-type-argument number-or-marker-p nil

[rkeks]

Can't open any books. Error during redisplay: (eval (list (propertize " " 'display '((space :align-to 0))) (fb2-reader-header-line-text))) signaled (wrong-type-argument number-or-marker-p nil) Ubuntu 20.04.4 Emacs 28.1 from snap.

Interesting, have same Ubuntu version on my home PC, just installed emacs 28.1 from snap and all works as expected. Can you reproduce this again with enabled debug-on-error?

[jumper047]

Seems like it connected somehow with #11 but I can't figure out what's wrong with it.

In addition to enabling debug-on-error set async-debug variable to 't

with "clean" init.el works properly. looks like problem with using "counsel" package

[jumper047]

If you have enough time/willing you can "bisect" your config to figure out which part causes an issue (by bisecting I mean erase one half, run, check, if issue disappears take other half and bisect it again until part which causes this behavior will be found). I suppose counsel is not the cause, it was just used to find file to open.

ok. i cleaned my .emacs.d and checked init.el. so, i think, the problem was wtith "no-littering" package. after cleaning emacs dir i opened sample file from previous issue without any problem.
