        Hi,

it looks like there is something with the gstreamer code in the

WebKitGTK, or, possibly better said, the message contains a video/audio

stream, which cannot be played with the gstreamer. As your Evolution

works fine, it can be closed, the problem is surely on the WebKitGTK

side. A backtrace of the corresponding WebKitWebProcess process might

help, but getting a backtrace from a Flatpak application is too

complicated.

I did manage to isolate the message that causes the freeze,  from external appearances
there is no audio or video.   However, I still need to dig into the internals of the page.

Externally,  it appears to be a block of text,  big graphic, block of text, big graphic, one
last block of text and a signature.
