Even if there was a finalise() method, if you tried to load/unload/load it will probably crash straight away as it tries to re-register a supposedly static type.

I only load and unload. Is this the same or another bug furthermore? I will open a bug report for this issue. Maybe it will be fixed some day :-) For now i will run the evolution2-opensync-plugin in a own process.
