Unhandled exception when disabling sync

[fritzophrenic]

I currently have configured to automatically sync on both open and save. I wanted to temporarily disable sync on open so that I could restore a backup copy of the database.

If no database is open, I cannot disable sync. Trying to open the KPGoogleSync configuration without an open database shows an error message, "You first need to open a database."

To fix this I tried opening a local database file which does not have a stored KPGoogleSync configuration (it is for local-only passwords). I can access the KPGoogleSync configuration, but after I select "Disabled" in the Auto Sync menu, and press OK, I get a message: "Remove Google Account association from KeePass config?". If I select "No" then nothing happens at all; the configuration dialog remains open. If I cancel, sync is not disabled.

If instead of "No" I select "Yes" for removing the Google Account association, then I get an unhandled exception:

System.NullReferenceException: Object reference not set to an instance of an object.

I would like a way to disable sync prior to opening my database, to prevent the automatic sync on open when needed! And needless to say, the plugin shouldn't crash.

You can temporarily disable sync by holding down the Shift-Key while opening the database.

You could also manually edit the KeePass.config.xml and remove the Item with the Key GoogleSync.AutoSync

I fixed the NullReferenceException problem and the fix will be in the next release.

There seems to be a regresstion/complexity to this error on Keepass 2.40, GoogleSyncPlugin-3.0.1.

If there is NO google account in DB, therefore no uuid for it.
Then after trying to setup the OAuth.
It asks to remove the Google Account association, then I get the same unhandled exception:
