Created attachment 1546 [details] email triggering the issue the attached msg causes Claws to hang when remote content is enabled in the fancy plugin
That email works for me... Loaded it into my local IMAP server and tested with Claws 3.12.0, webkitgtk 2.4.9, NixOS master.
@Khumba, the images load, and you're able to go to other emails once the email has finished loading? for me, it the UI gets stuck at "loading 50%", it shows no images, when I click on other emails, it doesn't open them. it takes a while for cpu to climb to 200% though, i wonder if that only happens when i switch to another window and then back. but the UI always hangs for me. i just tried it again with Claws Mail version 3.12.0 System Information GTK+ 2.24.28 / GLib 2.44.1 Locale: en_US.UTF-8 (charset: UTF-8) Operating System: Linux 4.2.1-1-ARCH (x86_64)
Okay, bug confirmed on Gentoo (all the same versions as in your and my posts, except LANG=en_CA.UTF-8 and kernel 4.0.5-gentoo).
When the crash occurs, Claws has two "pool" threads that are taking the 200% CPU.

Also happens with 3.11.1. (Sorry for the mail spam.)
