Comment 3 Gökçen Eraslan 2010-09-08 09:45:21 UTC 
I can also reproduce the bug with latest polkit(0.98), polkit-qt-1 and polkit-kde-1. I can say that Polkit KDE agent is not working with new polkit at all.

When I print the content of m_userModelSIM before and after the AuthDialog is shown, everything is OK, I can see user names with identity->toString(). 

But, when I try to print identity->toString() method of userModelSIM items at the beginning of AuthDialog::on_userCB_currentIndexChanged slot, just after I clik on a user on the AuthDialog, polkit says:

** (process:18090): CRITICAL **: polkit_identity_to_string: assertion `POLKIT_IS_IDENTITY (identity)' failed

I couldn't figure out the reason behind.
Comment 4 Radek Novacek 2010-09-08 17:29:35 UTC 
Can you try it with snapshot of polkit-qt-1 from kde repository? For me it prints: 

GLib:ERROR:gvarianttypeinfo.c:186:g_variant_type_info_check: assertion failed: (0 <= index && index < 24)

After manual restart of polkit-kde it work normally for me. I'll have to dig deeper to find what is wrong with it.
