Image information not identifying lens

[Kape60]

Describe the bug

Image information is not showing the description of the lens for following lenses:

• HD PENTAX DA* 11-18mm f/2.8 ED DC AW
• HD PENTAX DA* 16-50mm f/2.8 ED PLM AW
  It appears as "Unknown (0x08c4)" for the 11-18mm and "Unknown (0x08c3)" for the 16-50mm.

On the other hand, in the lens correction module, the two lenses are in the the list of PENTAX lenses and I can activate manualy the lens correction. But the two lenses are not identified automaticaly in the lens correction module.

That issue does not happen with other lenses.

Steps to reproduce

1. load an raw taken with the mentionned lenses
2. activate lens correction
3. red label appears "camera or lens unknown"
4. scroll the lens list and choose the lens. Now correction works
5. look in Image information for the lens: it is unknown

Expected behavior

DT should identify automaticaly the lens as long the lens is in supported lensfun list

This is not really a dt issue - please file an issue against exiv2 w/ samples, or even better, a patch directly.

Btw, you can always use the exiv2 config file workaround in the meantime.

FYI, the 11-18mm was already added to exiv2 (but only since v0.28.0), and I just added the 16-50mm (no ETA when that'll be actually released).

As the Windows installer is still stuck on exiv2 0.27.7 (for some other reason), one will just have to use the config file workaround for the foreseeable future...

Thanks.
