'Application' is empty and 'Folder Watch Limit' appears to be a html link, but does nothing when clicked.PolicyKit1-KDE
An application is attempting to perform an action that requires privileges. Authentication is required to perform this action.
Action: Folder Watch Limit
To date, all I have done is click 'Cancel' and get on with life. Today I decided to investigate. Here is what I found.
http://www.linuxquestions.org/questions ... 175505756/ talks about this in the context of Slackware. I tried setting max_user_watches to 20480: all that did was delay the message by a minute or so.
https://bugs.debian.org/cgi-bin/bugrepo ... bug=734134 attributes the problem to nepomuk and suggests turning off desktop search.
https://git.reviewboard.kde.org/r/106748/ talks about the problem and its proper solution. I'm not going to pretend to understand half of it.
Anyway, my solution has been to turn off desktop search (since I don't remember ever using it) and the problem has gone away. But it would be interesting to have a proper solution rather than just treating the symptoms.
