With commit 748d1b8 the function do_of_property_set_now is introduced. With this commit an unwanted free(data) is added wich leads to that an free on the value is done that is previously set to the property. As a consequence the command of_dump reads freed data an printis the value as hex. Fix this by moving free(data) to the right place like before the above commit.
