Do you still have this workspace around ?
The freeze happen with my working workspace. After restarting the IDE everything worked fine.
Does this mean you cannot reproduce it anymore ?
Yes, I can't reproduce it anymore
Got it again today. After killing the workbench and restarting everything worked fine again.
Sure enough, it did rebuild your index files from scratch. The interesting part is the original crash in the indexer. Maybe we should increase its robustness, i.e. if crashes, then captures this scenario and force reindexing all (at least you wouldn't need to exit and restart).
Closing, crash recovery was added.
