opencpn crash on rpi4 after 2 min (usb error?)

Sören.. Pavel..


I think the last record in the VDR file is the cause.
The GSV sentence is badly formed.
There's a float time instead of a ID number in field 8. See below.
Sören. To verify you would let the receiver transmit also GSV and there may be a crash.
Next step would be to take this info to the manufacturer and claim the device.
My assumption is the device's program hasn't cleaned an array since last GGA sentence or similar. The fault GSV is a mix between GSV and e.g. GGA

Pavel... more views?
