Thx for the tip ! Now, I'm getting somewhere. I see the following in 
.xsession-errors :
kicker: WARNING: cannot open applet:/usr/local/kde12beta2/lib/libkickertest.la
because of /usr/local/kde12beta2/lib/libkickertest.so.1: undefined symbol: 
__vt_10KickerTest

Using nm on the libkickertest.so file returns something similar :
<snip>
00001408 T __pure_virtual
         w __register_frame_info
=>      U __vt_10KickerTest
         U __vt_10KickerTest.12QPaintDevice
         U __write
00002798 A _edata
<snip>

I'm not an expert in libraries, I don't have a clue what this means. What is 
the problem and what could be the cause of it ?

Best regards,
Bart De Win.
