Version:            (using KDE 4.1.3)
Compiler:          gcc (Ubuntu 4.3.2-1ubuntu11) 4.3.2 
OS:                Linux
Installed from:    Ubuntu Packages

Sorry if this is the wrong place to report this bug, as I'm, running gnome, but it is a kde app. Knode installed via synaptic.

Similar to bug report 174953 but differs in running knode in Ubuntu 8.10 (gnome/metacity) and only crashing after adding a new score rule (click apply then crashes after clicking ok), not when editing an existing filter.

Also, the only score rules that get added are adding groups, i.e. changing a score value or adding a comment do not get applied.
