When I updating my product that uses Nebula widget I get the following error:
An error occurred while collecting items to be installed session context was:(profile=DefaultProfile, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

Installing Nebula Grid into empty Eclipse works fine. Any ideas what can be causing this error?
