monotouch device only crash

I have an app which uses btouch'd bindings for WEPopover. You can find the bindings below with a SAMPLE application that works on both device and simulator:

https://github.com/anujb/monotouch-bindings

I am using that same dll in another app and it works on simulator but causes a crash on device:

This is a known bug in the current stable release (5.0.*). It is fixed in the latest beta (5.1.1) - have in mind though that it is a beta and there are known regressions (for instance, if your application is big, it might not be possible to upload it to device).

You may have success working around the bug if you change the linker options (to link all assemblies)

8 MyApp 0x00b450c8 monoeg_g_logv (goutput.c:135)

The mono runtime is trying to tell you something but that won't show up in the crash log (e.g. you might be running out of trampolines). Try running:

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

on a terminal window when running your application. The device log should contain the message and/or managed stack trace that will make this easier to diagnose.
