[Evolution] Key 'primary-tasks' in schema 'org.gnome.evolution.calendar' rejected

Hello,

I just installed Evolution 3.34.2 on GNU Guix and when I launch Evolution, a series of critical assertions 
fail with a final error:

Reinstallation changes nothing and so does a full system update. I'm not sure if it's an issue specific to 
GNU Guix so I would like to see if any of you has had this error before.

Thanks
