aRTS uses 100% CPU and freezes whole computer on KDE startup

Binary package hint: arts

Using Kubuntu Desktop, upgraded from Ubuntu 6.06 to Ubuntu 6.10 via "update-manager -c".

Whenever a KDE application calls aRTS (if I am in another Window Manager) or during aRTS startup (when I'm entering KDE) the system hangs for a few minutes. After that a message box appears saying "Sound Server Fatal Error / CPU Overload - aborting" and an OK button.

If I leave the message box alone I can use the system. If I click "OK" the system hangs again and, a few minutes later, the message box reappears.

Seems like there's something wrong with aRTS or libarts. This didn't happen prior to upgrading from 6.06 to 6.10.

I also noted that the libarts-ausiofile and the kdemultimedia packages weren't upgraded from 3.5.2 to 3.5.5 due to some dependencies not met. apt-get complains about the lack of various "-dev" packages that kdemultimedia and libarts-audiofile depend upon.

I tried to uninstall kdemultimedia (wich is only a metapackage, so no problem) and libarts-audiofile to see if the aRTS-hanging problem went away. The problem, unfortunately, persists, but now I can't reinstall libarts-audiofile due to those dependency problems.
