We are only talking of a one-time rebuild of the EXIF db, aren't we? So why 
not simply enable it for new setups (as the EXIF db will be filled with GPS 
data anyway in this case) and add a button "Enable GPS search". If the user 
clicks on this one, we display a message:

"Enabling the GPS search requires a rebuild of the EXIF database. This process 
can take some minutes. Do you want to run the rebuild now? --> Yes / No".

If that update is done, we add some value to the config (which is set by 
default for new setups) and don't display that button anymore.

And that's it. Or am I missing/misunderstanding something?

Cheers, Tobias
