Many thanks for providing this version that quickly! Unfortunately, I still
cannot access the photos via kio_kamera.

However, the libimobiledevice github issue might have been a red herring and
the real problem is in libgphoto2: "gphoto2 --list-files" only works
erratically. The error message is 
*** Error ***              
PTP Invalid Storage ID
*** Error (-1: 'Unspecified error') ***  

I will open a new bug report and close this one. If turns out to be a problem
in libimobiledevice, I will reopen it.

Sorry for the noise and thanks again for your prompt response!
