Hi,
try to edit the lensfun-data in "/usr/share/lensfun".
In file "compact-panasonic.xml" the entry
<camera>
<maker>Panasonic</maker>
<model>DMC-LX100</model>
<mount>panasonicDMCLX100</mount>
<cropfactor>2.21</cropfactor>
</camera>
Points to:
<mount>panasonicDMCLX100</mount>
Add a new <lensdatabase>-File (or edit in compact-leica.xml?).
Copy model "DMC-LX100" as model "Leica D-Lux typ 109" into the new file.
Copy <mount>panasonicDMCLX100</mount> into the new file.
The model must match exactly the text from the exif-Data.
Your changes will be erased with the next update of lensfun. Make a copy.
If it works, give a ticket to the lensfun-projekt.
For a while the name of my new mft-lens did not match excatly between
lensfun-data and exif-data. Editing this files helped my using
lens-correction in darktable until the error was fixed in lensfun.
