[Users] Clicking a link in claws-mail opens it in default browser after a very long wait

[Removed GDPR]

Hi,

I am experiencing this issue on openSUSE Leap 42.3 (using KDE Plasma
desktop). When I click a link in a mail message it opens after 20-30
seconds (or more) in the default browser (Chromium).

Has anyone any idea if this is a bug or how to fix this?
