How to reproduce: 1. Remove ~/.config/sigrok/PulseView.conf to start with a clean slate. 2. Start "pulseview" (no options) 3. Open the file uart/voltcraft_vc940/voltcraft_vc940_multiple_modes.sr from sigrok-dumps. 4. Move the "TX1 (IR)" trace below the "12" trace. 5. Close PulseView. 6. Start "pulseview" (no options) again. Expected result: The trace order is the same ("TX1 (IR)" is below "12"), which is not the case.
