Not all attributes published when spaces are contained in attribute values

I've got a Quirky smart outlet (Zigbee) that reports the following from aprontest:

However, it only reports the following on the Mqtt topic home/wink/1/status
{"ApplicationVersion":7,"HWVersion":1,"ManufacturerName":"Quirky","StackVersion":2,"ZCLVersion":1}

Publishing anything to the home/wink/1/1/set results in what appears to be a no-op.

I think I've identified the issue (although, my data points are admittedly limited). It seems that as soon as there is a string attribute whose value contains a space, the mqtt daemon decides it's had enough and stops processing attributes.

ETA: Confirmed my suspicion. For now I'm editing the sqlite DB on the Wink directly to remove the spaces.
