After upgrade from kde-base/kdelibs-3.5.9-r4 to 3.5.10-r6, file associatins and installed application lists are empty in KDE applications. For example krusader losts all file associations. After trying to open a file the "Open with" dialog pops up but even in this dialog the list of "Known Applications" is empty. This bug is probably similar to #239849. Following the advice from it -- copy /usr/kde/3.5/etc/xdg/menus/applications.menu to /etc/xdg/menus/ -- fixed the problem. Note I'm not using full KDE, just WindowMaker and some KDE applications. $ emerge -pv kdelibs ...
