Did TrustBinaries = false fixed the issue?
As you did observe, TrustBinaries is not only a major security problem,
it also forces the use of binary code wrongly stored on the asset at grid.
so the only fix with TrustBinaries = true, is manual inworld recompile.
0008026: "Runtime Error in script... Could not load type 'list' from
assembly..." Script fails to function - MantisBT (opensimulator.org)
<http://opensimulator.org/mantis/view.php?id=8026>
you can not set it true after a upgrade. A rez from inventory will
trigger the issue again.
