Probably a long shot, but ...
Check the entry in the EXIF data of your photo file has the same case,
and syntax, as the entry in your <lensdatabase> file.
Look for Lens type or Lens ID. (IIRC)
This caused me grief in the past where the entry was lower case in the
photo EXIF data but did not match in Lensfun.

Hi,
I tried also without the variant line. Same thing, the camera appears
in the lens correction module, but the lens dropdown is empty. I doble
checked the spelling of the camera and compared the entry with others,
but I really can't see why this is not working.
Should I open a bug? Or is still an operator error?

The variants apparently don't work, see:

But they shouldn't be needed in this case anyway.
Otherwise, not sure why that wouldn't work.

For compact cameras, you also need to add the entry for the camera
itself along with the lens:
<camera>
<maker>Panasonic</maker>
<model>DMC-TZ100</model>
<mount>panasonicTZ100</mount>
<cropfactor>2.75</cropfactor>
</camera>
Also, you might have to remove that 'version="2"' parameter to get
darktable to load the file.
Ok, now I have the camera but not the lens (
http://pix.toile-libre.org/?img=1495308076.png ) --- The second
dropdown
is empty.
I tried to add a <variant> record to no avail.
Any further hint? Thanks!
