Short description of error
in f-curve editor, dope sheet and NLA editor (only tried these three), if you're trying to rename the key datablock (shape keys) by ctrl-clicking on the entry, the object's name is displayed and modified.
Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps
See attached blend file: ctrl-klick on "Key" in action editor etc. The editable text will be "Cube", and if you change it, the Cube object's name is changed.
