I don't use and have no installed plugins whatsoever. Or, do you include Modules to Plugins class? Only standard supplied with DVBDream installer Modules are installed, with only default Modules activated.
The bug is really easy to reproduce. It happens EVERY time regardless whether DVBDream is exited from rendered or renderless mode. I have really no choice, but only to reproduce it each and every time.
It was posted somewhere that DVBDream 1.4i supplied with Prof Cards on Setup DVD does not crash. So its probably easy to pinpoint the bug by comparing versions.
