KDE application menu blank

[Tim Goodaire]

Hello,

I'm running FreeBSD 6.0, and I'm having a problem with kde 3.4. The application menu is blank. 
The applications are installed, it's just that KDE doesn't seem to know that they're there.

I've tried googling for an answer to this, and searching bug reports but haven't found anything
relevant. I imagine that the solution is something like "run command X to rebuild the menus", but
I don't know what "X" is.

Any pointers would be much appreciated.

Tim
