After every login KDE executes /usr/lib64/kde4/libexec/kde_nepomuk_filewatch_raiselimit and tries to get user the rights using Polkit to install /etc/sysctl.d/97-kde-nepomuk-filewatch-inotify.conf although it is already present and /proc/sys/fs/inotify/max_user_watches is already set to 32768. This should only happen once and the code should check if limit is already raised before showing the polkit dialog. I will look into the code when I have some time and try to provide a patch. Reproducible: Always
Can you please provide some more information, such as emerge --info and the specific error messages you are receiving? (I am having difficulty reproducing, for example I do not have any KDE-related files installed into /etc/sysctl.d)
I am not sure when it happened but this problem does not occur anymore on my system. I hope I did not forget some workaround I may have created. I am closing this bug now and will reopen it in case the issue reappears.
