This is a pretty insignificant bug, but nevertheless causes a crash every time on my end.
Running 10.3.1 on MBP 13" Retina w/ Mavericks.
1. Open a General Tool
2. Click in the Text
3. Click on Word Chart or Diagram in the toolbar.
I realize that these options don't work with General Tools, but instead of giving the error message, it causes a crash.
