I removed it but when i clicked on Apply, ark came back and ~/.local/share/applications/mimeapps.list i have : [Removed Associations] interface/x-winamp-skin=kde4-ark.desktop; If i remove the association and in a different session do a kbuildsycoca4, ark come back. interface/x-winamp-skin is not in ark.desktop files in Mimetypes= 685972 1 faure 2008-12-23 20:05:52 +0000 And I suppose ktraderclient --mimetype interface/x-winamp-skin | grep DesktopEntryPath shows ark.desktop, right? Initially you had simply added ark to this mimetype in the filetypes editor? So somehow ksycoca4 remembers this wrongly. Does "kbuildsycoca4 --noincremental" help? Please also experiment with changing mimeapps.list by hand, not using the filetypes editor at all, and running kbuildsycoca4 after making changes, and running ktraderclient to see what was recorded. Here's also a patch to get more debug output from kbuildsycoca4 (in both modes, incremental and noincremental, if noincremental makes a difference). http://www.davidfaure.fr/tmp/kded_more_debug.diff To be used like "kbuildsycoca4 2>&1 | tee log". 685985 2 kde 2008-12-23 20:21:16 +0000 ktraderclient --mimetype interface/x-winamp-skin | grep DesktopEntryPath DesktopEntryPath : '/usr/share/applications/kde4/ark.desktop No it was already with this mimetypes, i didn't added nothing for this one I done a test ( don't know if this can help ) i added an association in interface/x-winamp-skin, i added amarok and i applied. Amarok show OK on the window. i done your test and got the same result: ktraderclient --mimetype interface/x-winamp-skin | grep DesktopEntryPath DesktopEntryPath : '/usr/share/applications/kde4/ark.desktop Then i tried kbuildsycoca4 --noincremental and now the previous test give an other result: ktraderclient --mimetype interface/x-winamp-skin | grep DesktopEntryPath DesktopEntryPath : '/usr/share/applications/kde4/amarok.desktop' DesktopEntryPath : '/usr/share/applications/kde4/ark.desktop' For the next test i changed in : interface/x-winamp-skin=kde4-amarok.desktop;kde4-ark.desktop; into interface/x-winamp-skin=kde4-amarok.desktop;kde4-ark.desktop;kde4-konqueror.desktop; i ran kbuilsycoca4 and nothing changed, i still obtain : ktraderclient --mimetype interface/x-winamp-skin | grep DesktopEntryPath DesktopEntryPath : '/usr/share/applications/kde4/amarok.desktop' DesktopEntryPath : '/usr/share/applications/kde4/ark.desktop' I am building a new rpm with your patch and then comment here 686007 3 faure 2008-12-23 21:06:03 +0000 SVN commit 900848 by dfaure: Fix removing an implicit association (derived mimetype) -- a bit like 164584 which had a unit test, but obviously 178560 was slightly different...
