[opensuse-support] Broken menu titles in okular

Some time ago I was fiddling with okular's settings [Configuration/Configure Okular]. I'm not sure what I did, but since then the 'File', 'Configuration' and 'Help' menus have had their titles replaced with the words 'No text'. 'Edit', 'View', 'Go', 'Bookmarks' and 'Tools' are unchanged. The menus still work. If I knew where these variables were stored I could remove that file and re-install okular. Removing and re-installing doesn't work, which means the changes I made are persisting, which is annoying. -- Bob Williams
