Well, it’s the Snapshot tool that’s upset about something to do with trying to read device parameters? It might be related to the automation data you have feeding into Bidule? Or, maybe, how one of those random VSTs presents it’s current settings to Snapshot?
Yup, thats my tool, hating your pluginz 
If you can replicate this error then let me know what steps you take and I will look into it. Cheers
