SUMMARY
The following is a list of files that over write each other from frameworks-syndication and syndication (from KDE Applications.

STEPS TO REPRODUCE
1.  Install frameworks-syndication
2.  Install syndication
3.  Look at the files installed by both.

OBSERVED RESULT
These are the conflicting files;
