However it would be more interesting to find out why. Before disabling the plugin, could you try the following:

In the root of the ktorrent directory tree is a file named CMakeLists.txt, try adding the following line to it.

remove_definitions(-DQT_NO_PHONON_VIDEO)

Add it right before this section:

add_subdirectory(libktcore)
add_subdirectory(plugins)
add_subdirectory(ideal)
add_subdirectory(ktorrent)
add_subdirectory(ktupnptest)
add_subdirectory(plasma)
add_subdirectory(ktmagnetdownloader)

Then rerun make
