I think there once was a menu entry to reload the thumbnails but can 
not find it any more.

As UFraw does no know anything of the tags set by digikam, the 
converted jpeg will not include this data. My way of using the tags is 
to extract the exif data via command line utility from the already 
available jpeg, run UFraw and add the extracted exif data back to the 
newly generated jpeg file. This implies, that you already use a jpeg 
file which tags are set to the same value than the raw file.

I think most of the problems will disappear if digikam support side 
car files (which will come the sooner or later).

To handle raw files I use a make file. this automates all the needed 
steps to a given amount. Up to now I am not finished with it.
