Mission Planner 1.2.12 crashes during start in Mono.

[GoogleCodeExporter]

Updated 1.2.11 successfully, but 1.2.12 would not start.
Also, a clean download of 1.2.12 won't start - crashes with the same error

i might have a fix for this in 1.2.13 - by not using the docking ability, there 
maybe other problems though

Great - :) Will test and let you know once it is out.
I also reported the problem to mono team.
Please, take a look at the way "terminal" features behave under mono, things 
work, but is much less predictive, it seems you need to click once or twice on 
"tests" or "show settings" to actually get to type something.
