Hmm, it appears that kyum is just a GUI front-end for yum (i.e. it 
invokes yum itself to do the work), compared with say yumex, which uses 
yum APIs but not the yum executable itself. So kyum doesn't need the 
same SELinux context as yum, unlike yumex. Apart, that is, from the need 
to read rpm/yum log files.

So give this a try:

# chcon -t rpm_exec_t /usr/bin/kyum

Then try kyum again, and make sure it still works OK for 
installing/removing packages (try it on something you don't care much 
about), as well as being able to read the yum log.
