SUMMARY
Have two nikon cameras connected via usb to the computer running Kstars 3.7.1
With the update to 3.7.1 from 3.7.0 only one camera can connect at ones.
By deactivating the successfully connected camera in indi settings the other
one can be activated and used.
Suspect a introduced bug, perhaps in indi_nikon_ccd ? but really don't not at
all.

This bug makes Kstars quite useless for guided astrophoto for me.
