Hello Tom,
This affects a few* projects when building for devices only (simulator
builds are fine). MonoTouch 4.2 ('beta' now,but should be moved to
'stable' soon) already has the fix for this. More details in:
http://bugzilla.xamarin.com/show_bug.cgi?id=604
Regards,
Sebastien
* no one could provide me with a test case but I'm 99% confident that
this is fixed. If you can attach a test case to the bug report I'll be
able to confirm this (100%).
