Because you uninstalled rekonq, supposedly to use another browser, however you did not configure the other browser as actual default browser for KDE. So kdelibs tries to launch its default browser (still set to rekonq as per global default setting), doesn't find it, whines about it, moves on to try alternative ways of opening the URI (which will at some point involve mimetype probing which will result in usage of the mimetype priority list.
Or to make the difference clear: there's technically two ways of opening any URL in KDE software. There's openBasedOnMime(URI) and there's openBrowser(URI). Former relies solely on the mimetype of the URI. Latter relies first on the default browser setting, secondly on a mimetype probe and thirdly (IIRC) on a fixed list of possible binary names or somesuch nonesense. The other (somewhat less likely) option is that you upgraded from a previous release and did not get rekonq pulled in because you were missing essentially key packages used for upgrade orchestration (this actually will be less likely with upgrades to 14.04 because of a heuristics improvement in the upgrader). The technical end result is the same though, all attempts to launch the default application will try to access an non-existent binary about which kdelibs rightfully issues an information dialog. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kde-baseapps in Ubuntu. https://bugs.launchpad.net/bugs/942336 Title: Could not find the program 'rekonq' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kde-baseapps/+bug/942336/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
