Comment 1 Oliver Goetz

Precondition:

 * open TS in TSE
 * add some TCs into the TSE
 * save so the TS is not dirty

Workflow:
 * expand view on TS in TSB
 * try to delete one or more of the TCs from the TS in the TSB

This issue is currently not reproducible with the given workflow - so I added a potential NPE safety for getDisplayableLanguages:392
