I think I will concentrate on the "database disk image is malformed" error for now - I haven't seen the other errors before. Before running a test, please power off your IPad/IPhone, and disconnect the usb cable. Then reconnect, power on, start Marvin etc.
I have uploaded a new pylib.zip to dropbox (
https://www.dropbox.com/s/y03anlaxhh...pylib.zip?dl=0). This time I have used a different method of locking the remote mainDb.sqlite file on the idevice. Thanks for trying this.
PS, the alpha dlls can be ignored.
