U means undefined, V is virtual and W is weak.

Since you're listing kded_walled.so, this are how they're supposed to; the 
symbols are imported. Please list libkdeinit_kded.so, which is where the 
symbol is supposed to be:

$ readelf -a /usr/local/kde3/lib/libkdeinit_kded.so | grep TI10KDEDModule
00021b44  00021801 R_386_32          00021be0   _ZTI10KDEDModule
00021ba4  00021801 R_386_32          00021be0   _ZTI10KDEDModule
   536: 00021be0    32 OBJECT  WEAK   DEFAULT   21 _ZTI10KDEDModule
   641: 00021be0    32 OBJECT  WEAK   DEFAULT   21 _ZTI10KDEDModule

The important thing isn't the object's weakness, but its visibility. In 
this case, it's exported ("default").

It shouldn't be defined in kded_walletd.so.
