FAIL since Kubuntu 20.10 ONLY Safe-Mode possible
Since the Kubuntu Update 20.10 "Grovy Gorilla" Thunderbird ONLY starts in SAFE MODE. Normal start gives this error:
XML-Verarbeitungsfehler: Nicht definierte Entität Adresse: chrome://messenger/content/messenger.xhtml Zeile Nr. 905, Spalte 3:

Disableling all extensions, add-ons doesn't work.
Any clues?
