The documentation for PyQt5 states that the .text() method on (what I presume) is an appropriate qt widget returns a `QString`. This object type is not recognized by sqlite3.py hence you get an error message telling you that you have used an "unsupported type" since only native Python types (unicode/str/int/long/float/None/buffer) are "supported" and the type you have used (QString) has no converter/adapter/protocol registered to transform it to/from a standard supported type.
