22732	ISE: The layer has already been destroyed	watmildon	Tyndare	"==== What steps will reproduce the problem?
I haven't tried to repro but wanted to capture the things I was doing.
1. Have a data layer with buildings in and such in it
2. Have a MWAI layer with address info in it
3. Use the conflation plugin to merge data in the data layer
4. After uploading, delete the data layer

==== What is the expected result?
Nothing

==== What happens instead?
Exception

==== Please provide any additional information below. Attach a screenshot if possible.
