Unexpected KeyError

[ghost]

Describe the bug
I was just working with maestral daemon and maestral_qt running in the background, when maestral throws a notification saying that an unexpected error had occurred, and then the try icon turned into a pause sign. Logs show as follows:

[TIMESTAMP] sync DEBUG: Created "[ABRIDGED]" on Dropbox
