Being a Slackware-based distro, I suppose you're not using PAM. If this is the 
case, you probably have a single option - using polkit-qt-1, as polkit-qt 
won't help here. Additionally, you will need a patch for making it work with 
Shadow, that has been posted and is a candidate for inclusion in the main 
polkit repository. Unfortunately polkit's maintainer has not yet taken action 
upon this.

However, from a first sight it looks to me the problem you're encountering is 
deep down in the polkit stack. To give it a small test, try using "pkexec", 
which is a sudo-like utility coming with polkit-1. If it segfaults, crashes or 
fails, which is quite likely given your experience, the problem is in the 
polkit stack.

Also let me remind you that if you wish to use polkit-1 with KDE you will need 
polkit-kde-1 as well (extragear/base/polkit-kde-1), otherwise you wouldn't 
have an authentication agent.

Hope this helps.
