**Short description of error**
Blender crashes after import 170MB sized STL file when interacting on right mouse click.
**Exact steps for others to reproduce the error**
Today I updated to new version. Old version allowed me to import the STL file and work with it. New version just closes without any message and all is lost. Procedure: Start Blender (Cycles Engine, Camera+Cube+light) > Import STL > Select 170MB big STL file > wait for 1 minute > After file is imported, right click on Cube (from startup default template) to delete it > Blender closes without message without request.
