When I open the containing folder for a download in Firefox it launches kdesvn (which then fails).
This isn't listed in the Applications tab in the Preferences window, and grepping kdesvn in ~/.mozilla doesn't find anything, so I suspect it's some kind of system-wide setting not particular to Firefox. Then again, I never see kdesvn being chosen to open a directory in any other circumstances.
What is responsible for choosing kdesvn as the application to open directories with?
For bonus points, is there a way to remove a given application from all file associations at once (I know how to do it individually)?
I am using Kubuntu 13.10
