Another bug and a question

Another bug that has been present for a while.

When importing images into C1 and selecting all images it will import all files stored in the source directory.
This includes unsupported files that is not managed by C1 after the import.

I sometimes use a sigma camera that produces X3F-files that is not supported by C1.
To be able to work with these files I convert them to tif and import the tifs to C1 by selecting import all in the dialog.
The import dialog shows only tif's.
I use "store inside catalog" for this step to have the trash working and rename files.

When I checked the filesystem outside C1 I found that all my X3F files had been imported into the catalog.
This is not a problem that causes crashes but since every X3F-file is about 50mb there is a considerable amout of disk space wasted.


A question:
Do anyone know if it is possible to replace the lensdatabase from 9.1.2 with the one from 9.2 (lensdatabase.cdx).
Im thinking of going back to 9.1.2 since openCL give a lot of errors in 9.2 but some of my lenses dont have a profile in ver 9.1.2 where openCL was working.
