I tried to import my settings from kontact on another computer and kontact now freezes every time. I attempted to correct for this using sudo apt purge kontact and by clearing .local/share/kontact but it still freezes. What else am I missing to create a truly fresh install? Running it through the terminal gives me the following output:

Icon theme "gnome" not found.
kf5.kxmlgui: this does not work on a KActionCollection containing actions!
