[mono-android] Stacktrace-less crash in 4.0.1 (I think)

[Steven Pack]

Hi All,



I got the dreaded stack-traceless NullReferenceException again on Monodroid
4.0.1Š At least I think I that's what I'm onŠ



MonoDevelop About window says:



Mono for Android: 4.0.1.234125318

Build information:

Release ID: 20805000

Git revision: c4deb930539ae87247b0bc43919dfcb98df215c2

Build date: 2011-12-09 23:27:52+0000



So, that looks good, but the assemblies themselves still say 4.0.0.0 (should
they be 4.0.1.234125318?)



System.Core                                4.0.0.0
/Library/Frameworks/Mono.framework/Versions/2.10.6/lib/mono/gac/System.Core/
4.0.0.0__b77a5c561934e089/System.Core.dll

glib-sharp                                 2.12.0.0
/Library/Frameworks/Mono.framework/Versions/2.10.6/lib/mono/gac/glib-sharp/2
.12.0.0__35e10195dab3c99f/glib-sharp.dll

System                                     4.0.0.0
/Library/Frameworks/Mono.framework/Versions/2.10.6/lib/mono/gac/System/4.0.0
.0__b77a5c561934e089/System.dll


When I run the app, my versions are:


Console.WriteLine (GetType ().Assembly.ImageRuntimeVersion);

Console.WriteLine (GetType ().Assembly.GetName ().Version.ToString ());

Console.WriteLine (typeof(Android.App.Activity).Assembly.GetName
().Version.ToString ());

Console.WriteLine (typeof(Mono.Data.Sqlite.SqliteCommand).Assembly.GetName
().Version.ToString ());



I/mono-stdout(  495): v2.0.50727

I/mono-stdout(  495): 1.0.4366.40581

I/mono-stdout(  495): 0.0.0.0

I/mono-stdout(  495): 2.0.5.0





And here is an example of the crashŠ no change from 4.0. It only ever
happens during resume, so I'm sure how to go about a repro.



Help!
