Some Ekos profiles with manual connections cannot be assigned an optical train.
 KStars then crashes when attempting to capture an image.  The steps to
reproduce below are one example.  Similar cases where the train does or does
not load are also given.

STEPS TO REPRODUCE
1.   Launch Ekos
2.   Create a profile with only Mount=Telescope Simulator and Camera 1=CCD
Simulator.  In the Profile Editor, Uncheck Auto Connect. 
3.   Start Ekos
4.  In the INDI Control Panel, Connect both the CCD Simulator and Telescope
Simulator
5.  In the CCD panel, attempt to capture an image or a preview.

OBSERVED RESULT

The Optical Train window does not appear when the profile is started.  The
Train field is greyed out in all panels.  It shows no value and cannot be
edited.  In the CCD panel the cooler fields are also greyed out, and the Live
Video button is crossed out.  KStars crashes immediately when the Preview or
Start Sequence buttons are clicked.

EXPECTED RESULT

I would expect the result to be the same when connecting the devices either
manually or automatically.  When the same setup is created with Auto Connect
enabled, Optical Train window appears when the profile is started for the first
time.  The Train field is populated in the Ekos panels and can be edited.  The
Cooler and Live Video controls also work.  Capturing an image works as
expected.

The crash seems to occur occur only when both a mount and a camera are present
and they are being connected manually.  The same behavior happens when a real
camera is used instead of the simulated camera.  If only a camera is used and
no mount, then it can be connected either manually or automatically without
crashing.  If I edit a profile that crashes and change the connection mode from
manual to auto, then everything works; the Optical Trains window appears when
the Profile is started after Auto Connect is enabled.  If I edit a Profile that
is working and change the connection from auto to manual then it still works;
the train information appears to be saved.
