This seems a case in which the backtrace is needed.. simply place a 'backtrace 
call' function at the top of the method called twice and see the classes the 
call has traversed before reaching your slot.

I personally use the console output of kdenonbeta/ktracer (install it):
1) in code:
  #include <ktracer.h>
  void MyClass::slotSomeName()
  {KTRACER_ENTER
       .... other stuff of the class ...
  }
2) compile and install knotes
3) at runtime:
# KTRACER=20 knotes
where 20 is the depth of the trace. Then watch the output (or use ktracer 
itself (experimental program) for full output decoding).

You can also use kdBacktrace() in place of KTRACER_ENTER, but the output is 
less nicer and you cannot adjust trace depth at runtime.

You should be able to debug it now! Ciao,
Enrico
