Perhaps kdelibs broke? offending commit is f9931c3d841ccb215a3bad14e0adc9dddb84091c
it introduces the following change: - QString categories = getField("Categories"); + QStringList categories = QString(getField("Categories")).split(',', QString::SkipEmptyParts); which in turn leads to the proxy model refusing to apply category filters: muon-discover(12215) shouldFilter: "KPatience" muon-discover(12215) shouldFilter: "Qt;KDE;Game;CardGame;" muon-discover(12215) shouldFilter: CategoryFilter false So, either that change was wrong to begin with, or kdelibs changed behavior. Categories as per the spec is a ; seperated list, however I seem to recall that the previous thing we used in KDE had , as seperator (might be utterly unrelated :P). The question is, does it actually return "Foo,Bar" on kdelibs 4.11, if so then I guess kdelibs should get fixed. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to muon in Ubuntu. https://bugs.launchpad.net/bugs/1283004 Title: Muon Discover does not show most apps To manage notifications about this bug go to: https://bugs.launchpad.net/muon/+bug/1283004/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
