Comment 1 for bug 2047274

Yeah, it looks like it would be good to add some better error handling to avoid having the unhandled exception put Pinta into a bad state

In this particular case, the issue is that the Night Vision effect (and other add-ins) were updated earlier in the Pinta 2.2 development cycle when I was restoring support for add-ins, but there have been changes since that cause incompatibility. I'll upload new builds of the addins once the translations are updated
Add-ins can specify a dependency on a specific version of Pinta (in this case, the Night Vision Effect's latest version requires Pinta 2.2), but development builds can have problems. The release checklist requires updating all the addins for the latest release so this shouldn't be an issue for normal users though
