error in process sentinel: ement--resize-image wrong type argument

[gcentauri]

Login with my user at my homeserver (running dendrite 0.9.6) open a room buffer, I start seeing this error happening periodically:

error in process sentinel: ement--resize-image: Wrong type argument: consp, nil
error in process sentinel: Wrong type argument: consp, nil

(fboundp 'imagemagick-types) returns nil for me

Using Emacs 28.1 and just installed the stable version of ement.el

Hi Grant,

Thanks. Could you enable debug-on-error and show me the backtrace when it happens again? Also, what build of Emacs do you have installed, i.e. from where?

[gcentauri]

Yeah, idk what was going on yesterday but toggle-debug-on-error wasn't triggering. I restarted things and got a backtrace this time though.

There's a lot of folded data in there, but I drilled down into the room bit:

#s(ement-room :id "!yWuuGCTDPPX6vuI3:cicadas.surf" :display-name "emacs" :prev-batch "t604_9995" :summary ((m\.invited_member_count . 0) (m\.joined_member_count . 2)) :state ... :timeline ... :ephemeral ... :account-data ... :unread-notifications ... :latest-ts 1662763202809 :topic "endless muckin..." :canonical-alias "#emacs:cicadas.surf" :avatar #(" " 0 1 (display nil))

This is a room on my homeserver, and it looks like the avatar bit is coming back nil.

My build of Emacs is from source, the 28.1 tag on the main repo.

I've been able to suppress the error for the moment by turning off the ement-room-list-avatars

[alphapapa]

Thanks.

Does that room have an avatar? If so, does it appear properly in other clients?

[alphapapa]

This was likely fixed by #147. If this happens again, please open a new issue. Thanks.
