Here are the steps to try and reproduce the bug:
1. Enable the search text box to appear in the upper-right corner of the window, in the toolbar.
2. Switch the language to Greek, clicking on the Magnifying Glass icon of the text box.
3. Type the asterisk symbol from the numeric keypad.
4. In my case, the program crashes every time the asterisk is typed as Greek input, whether or not other Greek characters have been typed before it.
