this symbol is not found by your applet. it refers to this method: 
KABC::StdAddressBook()

the 'v' in the symbol name is for "void" (e.g. no parameters).

wrong library. StdAddressBook is in libkabc, which is in kdelibs/kabc/ if you 
aren't linking your applet against libkabc then you'll have problems like 
this =)

a) this is KABC::StdAddressBook::self(bool), which is a different method from 
the one you are using
b) you don't want to be using strings but nm. if you use nm you'll see this:

aseigo@freedom:~$ nm /opt/kde4/lib/libkdepim.so | grep StdAddressBook
         U _ZN4KABC14StdAddressBook4selfEb

a-ha! 'U'. `man nm` tells us that `U` means "undefined". in other words, this 
is the -wrong- library. now if we do this:

aseigo@freedom:~$ nm /opt/kde4/lib/libkabc.so | grep StdAddressBook | grep 
self
0005d5d0 T _ZN4KABC14StdAddressBook4selfEb
0005d8f0 T _ZN4KABC14StdAddressBook4selfEv

'T' means "the symbol exists, and it's in the code (text) section of the 
binary". 

so i'm guessing you didn't link against kabc =)


happy new year.
