Hi,

 I have a Panasonix LX-7, which has a multi-aspect sensor.  (As
opposed to most budget cameras which achieve other aspect ratios by
cropping the result from the sensor)
http://www.chromaticabrasion.com/blog/2012/10/23/panasonic-lx3-lx5-lx7-multiple-aspect-ratios-explanation

 As such, I tend to switch between the modes (3:2, 4:3 and 16:9 -
there's also 1:1 but that is a crop) quite frequently.  I notice that
the LX-7 is now supported by lensfun - but that the only aspect ratio
in the database is 4:3.

 Does this mean that separate sets of distortion corrections also need
to be submitted for the 3:2 and 16:9 ratios? (I've never done it
before, someone else has kindly added the LX-7 at 4:3, but perhaps I
could give it a shot for 3:2 and 16:9). Or is the aspect ratio only
important for cropping the result?

 In digikam with the latest lensfun from SVN I seemed to get decent
correction in a test image despite the ratio of the image being 16:9.
It doesn't quite match the jpeg from the camera (I guess only
commercial software like Aperture or Lightroom with closed source info
from Panasonic can do that) but it's close.  It did leave some curved
black areas at the top and bottom of the resulting image, but
digikam's "auto crop" soon eliminates that.  If that's all I have to
do, I'm not really concerned about it.  But I don't really understand
how the distortion correction works.
