I'm don't normally run KWM (although I've tried, and it won't run either). I'm using Sid on i386, and I just upgraded to 2.1-final-1 using dpkg manually on .debs downloaded by http & ftp.
Whenever I try to start, say konqueror, I get the message: konqueror: error while loading shared libraries:/usr/lib/libkdecore.so.3: undefined symbol: getButtonShift__14QPlatinumStyleRiT1 This seems to apply to all KDE apps. I've tried purging and reinstalling, and it didn't help (although I could have missed something).
