System.Exception: Method Pin on type MS.Internal.NamedObject does not have a valid method signature

What You Are Seeing?

I can see the above error when trying to open the details of some packages with a mouse right-click. Oddly, the error does not happen when opening the details with a double click. More oddly, I can observe it only with some particular packages. So far I have experienced this behavior with: openorienteering-mapper, qgis, putty. After clicking “OK”, Chocolatey GUI crashes for good and must be started over. There is a side-issue, which might or might not be related: After starting the Chocolatey GUI again, the invalid package (the one on its details the Chocolatey GUI crashed) cannot be found with the search-box in the remote packages view.

What is Expected?

Details page opens and no error happens.

How Did You Get This To Happen? (Steps to Reproduce)

1. I opened Chocolatey GUI and then “chocolatey” (list of remote packages)
2. I searched for “QGIS”
3. I right-clicked the “QGIS” package and selected “Details”
4. The “System.Exception” happened
