Add a new package exception

[Dumller]

I am trying to add a package hierarchy from an add-in. When I add a new package to an existing package collection and call Update() an exception is thrown: "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." My add-in is written in C# using VS 2010.

EA.Package useCasePackage = FindPackageByName(pckgAnalysisRealization, aPackageName);
if (useCasePackage == null)
{
     useCasePackage = pckgAnalysisRealization.Packages.AddNew(aPackageName, "") as EA.Package;
     if (useCasePackage == null)
         return null;

     useCasePackage.Update(); // <- Fries here
     pckgAnalysisRealization.Packages.Refresh();
}

This is the pattern that I saw in the reference material. Am I missing something?

Just to add another clue, when I run outside of the debugger I get an EA dialog popup:

An error occurred while attempting to communicate with an Addin:
BHIEAAddins (BHIEAAddins.AddinMain)
"EA_MenuClick: Index out of bounds"
Please contact the add-in provider for assistance.

Yeah, I get that too when the name doesn't exist that I'm searching for - works fine if it exists.

Had to fall back manually looping through the packages collection
