Kubuntu 14.04, all updates till today (2014-12-22): Had same problem, but with audacious comming up, instead of dolphin. Deinstalled Audacious. Then Gwenview came up instead.
After some searching i found, that firefox is using /usr/share/applications/mimeinfo.cache from desktop-file-utils. This was line for inode/directory : "inode/directory=audacious.desktop;kde4-gwenview.desktop;kde4-dolphin.desktop;kde4-kfmclient_dir.desktop;" Same Problem for pdf, getting gimp instead of okular: "application/pdf=gimp.desktop;kde4-okularApplication_pdf.desktop;" Editing by hand, showed, that ff used always the first entry of this for directory. Same Problem with line "application/pdf=kde4-okularApplication_pdf.desktop;gimp.desktop;" Everey update triggering /var/lib/dpkg/info/desktop-file-utils.postinst created /usr/share/applications/mimeinfo.cache from completely scratch. No changes by hand survived. Applications got sorted alphbetically in each line again. Ugly (but system wide) solution for me now : I added some lines in /var/lib/dpkg/info/desktop-file-utils.postinst, after "update-desktop-database -q" : --- set -x grep -v "application/pdf=\|inode/directory\|MIME Cache" /usr/share/applications/mimeinfo.cache >/usr/share/applications/mimeinfo.cache.xx cat /usr/share/applications/mimeinfo.cache.willi.kopf >/usr/share/applications/mimeinfo.cache cat /usr/share/applications/mimeinfo.cache.willi >>/usr/share/applications/mimeinfo.cache.xx sort /usr/share/applications/mimeinfo.cache.xx >> /usr/share/applications/mimeinfo.cache rm /usr/share/applications/mimeinfo.cache.xx set +x --- I can repair that for my family and the school i'm supporting, but I consider that very annoying especially for unexperienced users. Please get that repaired.
