Package: Evolution *Hangs and goes to 100% CPU usage on compose* I confirm this bug. I too am running bookworm, with Evolution 3.45.3-2, and have exactly the same issue when trying to compose with new>mail message. This started happening a couple of days ago (15 Sept 2022). I apt update daily. (I've had to use a web browser to send this email.)
I can confirm this also happens from the command line with evolution mailto: - CPU goes to 100% and compose does not start. There are no command line errors - I have to terminate with CTRL-C. Regards, Andy, Birmingham, UK
