"java.lang.RuntimeException: uncategorized problem while processing"

[FpunktBpunkt]

It looks like a bug of a third-party implementation but are you aware of those massive reported issues in public-transport-enabler?

Transportr is basically very good but currently unusable for me.
See: schildbach/public-transport-enabler#730

Describe the bug
Java Exception when looking for any route using "KVV" (Europe/Germany).
