Created attachment 1556 [details] The offending message. When I try to click to read the attached message in claws-mail-3.12.0-1.mga6 on Mageia Linux x86-64 6/Cauldron, then claws-mail gets stuck with an unresponsive UI and while consuming 100% of the CPU. Please let me know what else you need and please look into fixing it.
Not reproducible with Fedora 24 development (x86_64). First asking about the problem on the Claws Mail users@ mailing-list would have been a great idea. Gather some more details. Do you use the "Fancy HTML Viewer" plugin? Is it enabled? If so, what are your "Preferences > Plugins > Fancy"? Can you examine the plugin's dependencies, such as the version of WebKitGTK+ your Mageia Linux installation uses?

I'm not using the Fancy HTML Viewer plugin. The only plugin I have enabled is "AttRemover". Otherwise some details are: shlomif@telaviv1:~$ locale LANG=en_GB.UTF-8 LC_CTYPE=en_US.UTF-8 LC_NUMERIC=en_GB.UTF-8 LC_TIME=en_GB.UTF-8 LC_COLLATE=en_US.UTF-8 LC_MONETARY=en_US.UTF-8 LC_MESSAGES=en_US.UTF-8 LC_PAPER=en_US.UTF-8 LC_NAME=en_GB.UTF-8 LC_ADDRESS=en_US.UTF-8 LC_TELEPHONE=en_US.UTF-8 LC_MEASUREMENT=en_GB.UTF-8 LC_IDENTIFICATION=en_GB.UTF-8 LC_ALL= shlomif@telaviv1:~$ I'm going to attach a gdb backtrace soon and will test with a version of claws-mail that I built from source. Also - my desktop is XFCE - xfwm4-4.12.3-1.mga6 and I'm running claws-mail from KDE's konsole.

OK , some more info - this also happens with claws-mail compiled from source using this script: <<<< #!/bin/sh ./configure --prefix="$HOME/apps/claws-mail" >>>> Furthermore, it also happens after I unload the AttRemove plugin and restart claws-mail.
