Bug#629659: [src:kde4libs] Please provide a plugin mecanism for file filter, particularly bz/xz
Filed under the src package section because it is also a packaging problem.
Now kdelibs support of compression filter is done at compile time. You enable bz support but disable xz support.
If I want to support xz, I need to:
1. recompile the whole package (not nice for end user)
2. add xz dependencies to all user (not nice for a lot of user).
It is better to enable compression filter support throught a plugin mecanism with on demand loading of library.
I have forwarded this bug upstream at https://bugs.kde.org/show_bug.cgi?id=275215
