           Summary: SIGABRT by mini.c:3061 while starting up app
    Classification: Mono
           Product: MonoTouch
           Version: unspecified
          Platform: iPad
        OS/Version: Apple iOS 4.3
            Status: NEW
          Severity: Critical
          Priority: P5 - None
         Component: Runtime
        AssignedTo: mono-bugs at lists.ximian.com

Description of Problem:

When starting the app on iPhone/iPad, it crashes with a SIGABRT and an
assertion violation:
* Assertion at ../../../../mono/mini/mini.c:5054, condition `vtable' not met

Experimenting around, also the following assertion violation occurred:
* Assertion at ../../../../mono/mini/mini.c:3061, condition `target' not met

The two stack traces are attached below.

Steps to reproduce the problem:
1. Compile attached solution with monotouch, important: compile for debugging,
use the iPhone/Debug configuration
2. Upload app to device
3. Start app on device
4. SIGABRT is expected

The behaviour occurs if and only if the option "Enable debugging" in
MonoDevelop is checked.

Things I have checked which didn't work:
- restart device
- remove App on device, reinstall App on device
- rebuild solution
- delete obj/bin folders
- rename app identifier
- use different provisioning profiles
- restart MonoDevelop 

Actual Results:

The app crashes before any views are displayed.

Expected Results:

The app start up normally and displays the hello world view

How often does this happen? 

Almost every time the app is started. In one of ten cases the app starts
normally though.
