[MonoTouch] MonoTouch crash on launch on device

[Sebastien Pouliot]

Hello,

Is your application using native libraries ? If so is it possible it's
not available / different on one of your macs ?

Also can you attach the output of:

/Developer/MonoTouch/usr/bin/mtouch --logdev

to your reply. E.g. start the above command from a terminal window,
lauch your app (it will crash) then copy/paste the output in your
reply (or attach it).

Thanks
Sebastien
