While testing the IGB App Manager prior to the 8.5.0 release I noticed that an exception was being generated when trying to install an updatable plugin.

Furthermore, the plugin would not install, the Install button turns into "Installing...", but it just hangs there.

To reproduce:

1) Open the IGB App Manager and make sure that only the Bioviz repository is enabled (the Bioviz Development repository should be disabled).
2) Install a plugin.
3) Now enable the Bioviz Development repository
(*Observe: your installed plugin should be updatable)
4) Now "Uninstall" the plugin (don't update).
5) Now try to "Install" the plugin.

***Observe: The "Install" button has changed to read "Installing", but it just hangs here indefinitely. Furthermore, an exception is generated in the console:
