Comment 20 for bug 92932

I had this problem in an up-to-date-Kubuntu-8.04 since an kde upgrade as the original poster reported. The 'sudo chmod 4755 /usr/bin/kcheckpass' did solve the problem for me, thx Dragomir.

This should be included in an upgrade script. The bug had nothing to do with scim (in my case). Unlocking now works also while skim or scim is running.
