Reproducible: Didn't try
Comment 1 Markus Schorn CLA 2010-05-20 10:44:27 EDT 
Created attachment 169353 [details]
fix

The patch simply suppresses the exception when an attempt is made to parse a file of a project that is being closed. The model builder will bail out when the ast returned is null.
Comment 2 Markus Schorn CLA 2010-05-20 10:45:00 EDT 
Fixed in 7.0 > 20100520.
