Please install thumbnailers as (soft)dependency

[Luigi Toscano]

Hi all,

it looks like not all distributions install the available thumbnailers when 
packages that benefit from their availability are installed.

While thumbnailers are optional, if your packaging system provide 
soft-dependencies, please make sure that those packages (dolphin, 
plasma-integration, and probably others) soft-depend on the thumbnailers, if 
they are packaged in your distribution.

A (possibly incomplete) list of the repositories which provide thumbnailers is:

- kio-extras
- kdegraphics-thumbnailers
- kdegraphics-mobipocket
- ffmpegthumbs
- kuiviewer (from kde-dev-utils)
- kdesdk-thumbnailers

Ciao
