Steps
- Open two folders in dual display mode.
- Select a file or folder in the right lister and enter inline-rename (F2 for me).
- Middle-click the right tab in tab bar.
Result: DOpus crashes.
Note that DOpus has to be in dual display mode.
Also note that there must be exactly one tab in the right display and you must close the tab with middle-click ("close" in context menu is unavailable when this is the last tab).
