Interface hangs on Copter log file, but works with identical Plane log file

[qqqlab]

When loading the copter.bin file the interface hangs, but the plane.bin works fine. The only difference between the files is one MSG message, see: c.zip

NB1: It would be nice to be able to set the flight mode with MSG messages (in addition to the MODE messages). This to get away from the pre-defined ArduPilot modes. For example: sending MSG message "Flight Mode:flying-high" would show flying-high as flight mode in the app.

NB2: Thanks for your quick response on my previous bug report. In plotbeta it working now.
