I don't use PyKDE so this is a guess. The QMap is converted to a dict
which is what you are updating. The QMap is never updated from the dict.
There needs to be a separate API call (either real or added specifically to
PyKDE) to do this, eg

meta_data = oua.metaData()
meta_data["prop1"] = "val"
oua.setMetaData(meta_data)

...or...

oua.setMetaData("prop1", "val")
