Understood. I installed the beta of Kubuntu 17.10 and it seems to come with a 
reasonably recent Qt (5.9.1). Now it does not fail immediately. Still, as you 
correctly predicted, there seem to be communication problems. The -vv output 
is at the end of this mail, in case it is of use (pure gibberish to me). The 
"needs authentication - permissions" line makes me nervous - did it lose the 
PIN I entered in bluetoothctl?

By the way, there seems to be a strange bug(?): for the first failed download I 
get an information window. For each subsequent retry there is an additional 
window. E.g. for the 5th failed download it opens 5 information windows at 
once.
