Do you have a procedure that starts from an empty composition? Not really, I didn't manage to crash Rosegarden using an empty composition.
Please do not laugh, but to trigger this crash I use the zoom wheels very rapidly like a lunatic (!) from maximum to minimum. Sometimes Rosegarden crashes after 15 movements, sometimes it takes 30 seconds. If this is a bug and very rare, will it be named after me? Thanks and Greetings, Michael > Gesendet: Montag, 19.
