Dear Maintainer,

to reproduce the bug:

create default database NewDatabase.kdbx. Close keepass2 and copy
NewDatabase.kdbx to NewDatabase1.kdbx as target for synchonizing. Start keepass
again and:
- Tools / Triggers ...
- add Trigger and give it a name
- next
- add event
- chose 'saved database file' as event

and you will get the keepass failure 'The object was used after being
disposed'. Trigger cannot be defined and keepass chrashes and cannot be
restarted.
