There is indeed, as Rog suggested: menu > Settings > Settings Panel >

Unfortunately it's ambiguous: there is a checkbox to have photos
automatically imported when a device is connected, and there is a box
for a command to run, but no indication if these two are meant to be
connected (ie "download pix with this program").

Either way it's moot, because nothing happens anyway, no matter what.

I have upgraded to Xubuntu 15.10 since my original post; now syslog says:

It's that last one that puzzles me.

But in any case, it is an error when an unexpected, unwanted, and
unnecessary system call claims prior ownership of a device intended for
the end user. It is also an error when an application (eg Digikam) gives
up so easily; it needs to be more robust, and if necessary stomp all
over the bogus claim of ownership and gain control of the device.
