As far as I can tell the kpassdlg error affect kwallet, but not the other kded 
modules.  I have also experience many problems with kded modules not loading, 
such as kded_kcookiejar.

The error seems to be that the typeinfo for KDEDModule couldn't be found in 
the symbol, but I don't know how that jibes with -fvisibility (or 
--as-needed) since I can't find that symbol in my 3.3 installation either.

I have it working now that I've removed -fvisibility=hidden from my kdelibs 
Makefile (shouldn't that be a configure option?), but even adding the 
KDE_EXPORT macros to the KDEDModule class definition didn't help, so now I'm 
stumped as to how to fix it when -fvisibility=hidden is enabled.
