 1. Add, say, 3 shapefiles.

 2. Highlight the 1st one.

 3. Press F2 to change it's name - all is OK. You change the name, press
 Enter.

 4. Highlight another one.

 5. Press F2 to change it's name - nothing happens this time. Bad.

 6. Right click it > change name - OK, but the first letter you enter does
 not pop in. Bad. Anyway - finish changing the name, Enter.

 7. As F2 is not working anymore, right click another layer, start changing
 its name but don't confirm with Enter. Select another layer on the list or
 press ESC instead. This way you will end up with many layers in the course
 of name change, which should not take place - pressing ESC or selecting
 another layer while editing some layer's name should IMO cancel edits.
 Moreover, sometimes QGIS crashes in this circumstances:
