Hi everyone,

I am using TOPCASED 3.3 (EMF Compare 1.0.0v200906220949) and some NPE
are raised depending on the way I call model comparison

View : Project explorer => Action : Right click on UML file, Compare
with, Base from working copy => Comparison result : OK
View : Project explorer => Action : Right click on UML file, Compare
with, Latest from repository => Comparison result : OK
View : Project explorer => Action : Right click on UML file, Compare
with, Revision or URL => Comparison result : OK (Head and Revision)
View : Project explorer => Action : Right click on UML file, Compare
with, Local History => Comparison result : KO (NPE)
View : Project explorer => Action : Select 2 UML file, right click,
Compare with, Each other => Comparison result : OK

View : Team synchronizing SVN => Action : Double click on modified model
=> Comparison result : KO (NPE)
View : Team synchronizing SVN => Action : Right click, open in compare
editor => Comparison result : KO (NPE)

View : History => Action : Right click on UML file, Team, Show history,
Select 2 revision, right click, compare each other => Comparison result : OK
View : History => Action : Right click on UML file, Team, Show history,
Right click on a revision, Compare current with XX rev => Comparison
result : OK
View : History => Action : Right click on UML file, Team, Show history,
Right click on a revision, Compare current with Previous state =>
Comparison result : OK
View : History => Action : Right click on UML file, Team, Show local
history, Select 2 revision, right click, compare each other =>
Comparison result : KO (NPE)

This was failing somewhere in the label providers of UML2, and I can no longer reproduce this issue with the current builds of EMF Compare and UML2.
