After installing both bundle-kde4-ssl-x11 or bundle-kde4-ssl-mac, very few applications would launch successfully. Mostly they would complain about mime-types, i.e. 

Could not find mime type inode/directory

and half a dozen others. After finding hints online about linux kde packages needing to reinstall kdebase, I did the equivalent in fink, i.e. reinstalling kdebase4-x11. It was here that I caught the message

== KDE4 Applications Have Been Updated ==
You should start a new shell, or run /sw/opt/kde4/x11/bin/kbuildsycoca4 to update the KDE4 application database.

And that was the trick!

Update: maybe not. It looks like it worked just that once. Since then, it looks like dbus has stopped working? If, for example, I launch gwenview, I get


john-evanss-imac:web jevans$ gwenview
gwenview(5606) mac_initialize_dbus: warning: unable to initialize D-Bus environment!
Dynamic session lookup supported but failed: launchd did not provide a socket path, verify that org.finkproject.dbus-session.plist is loaded!

and this leads on to the same errors as before. Hmm….
