missing objectif name in properties

[frederic chaume]

Hi all

just notice that with the new lens I bought, (Olympus Zuiko 100-400) its 
name is missing in the properties
the lensInfo and lensModel is correct in the exif, but not in the 
propoerties , instead a number is shown, and I don't know what it 
relates too

I just installed the 8.1.0 (but didn't check how it was in the previous 
8.10 beta release I had before)

Any suggestion? should I create a Bugzilla?
