Where should I report kde 3.5.4/suse 10.1 bugs?

Hi all, I have a nasty bug on my two suse machines, a segfault in kcm_keys which was introduced by the latest update of kde 3.5.4 taken from the additional repositories of the suse build service (if this is its public name). Replacing kcm_keys.so and kcm_keys.la with the ones in the kdelibs rpm from the opensuse repository is a quick fix in case someone needs it. Where should I report this bug? In the suse bugzilla, in the kde bug tracking system or ? Also, this information should perhaps be added in the webpage about yast additional repos on the opensuse website. Bye and thanks Vincenzo
