Where to report bugs?

[Christopher J. Bottaro]

The launchpad.net site is for Ubuntu, no?  Where do I report Kubuntu bugs? 
For instances, Kopete is sending across   sometimes instead of spaces:

"Yes, I did.  She seemed really hungry."

Appears in my gf's Trillian chat window as...

"Yes, I did.  She seemed really hungry."

I figure this is a Kubuntu, not Ubuntu, bug because it's specific to a KDE
app?

Thanks,

P.S.  No it's not Trillian because it only started happening after I
upgraded to Edgy.
