Kickoff menu unstable

Hello, I'm currently using TDE 3.5.12 compiled on RHEL6. By default, kmenu is showing the classic KDE menu, which works very well. But when I switch to "Kickoff" menu, I have 2 issues: 1) The "K" button icon is automatically changed to the default KDE icon, and the word "Go!" is displayed alongside the button, even though I chose a custom icon and unchecked the option "Display text in K menu button". 2) Randomly (but quickly) when browsing the Kickoff menu, it hangs. Then the "kicker" process eats 100% cpu and I have to manually kill it and restart it. Re-switching to the classic menu makes both issues vanish ... Is anyone else having stability issue with kickoff ? (Note: I have the exact same behaviour with the current 3.5.13 SVN build) Thanks Francois Andriot
