QLowEnergyService::discoverDetails() never completes

About 1 out of every 5 attempts at using the example void Device::connectToService(const QString &uuid) call, and consequently the call to service->discoverDetails();, never completes. It continues to read the same characteristics and descriptors over and over again. Otherwise it works just fine the rest of the time.

I haven't had any issues reading the descriptors with gatttool repeatedly.

I have attached two text files with the log output.

The repeated attempts are separated by: Discovering descriptor values for "

"
works.txt & not-working.txt

Thanks in advance for any insight into this!
