You don't seem to have a look and feel package installed, so it fails to load the RunCommand QML and crashes. While this technically is a bug, Krunner is of no use without a UI and OS X has a similar application with Spotlight anyway. Nothing resolved here ... ;) IMHO, if it is expected and thus implicitly intended behaviour that krunner crashes without look and feel packages installed, there ought to be a dependency somewhere that forces the user to install at least one such package. I don't get the remark about "without a UI". Not having a L&F package shouldn't mean there is no UI, only that there is no easy way to control how the UI looks and feels, right? Also, I don't think SpotLight and Krunner have more than partial (and limited) overlap. SpotLight is a file and metadata indexing engine with a search interface, the most easily accessible of which corresponds roughly to Milou . I'm not perfectly sure what Krunner is *exactly*, but the name suggests its something to run (launch) things without using a terminal emulator. |
Application: krunner (5.5.4) (Compiled from sources) Qt Version: 5.5.1 Operating System: Darwin 13.4.0 x86_64 Distribution (Platform): MacPorts Packages -- Information about the crash: - What I was doing when the application crashed: The attached crash is systematic on OS X. This ticket is FYI and FWIW, serving at least the purpose of testing DrKonqi in a real-world scenario. Working on the plasma-workspace package in order to get DrKonqi to build I noticed that KRunner doesn't have any build-time dependencies on libraries that are not available on OS X (or "outside" of plasma). It built without issues, but this is the result when starting it (without arguments). -- Backtrace: Application: krunner (krunner), signal: Segmentation fault: 11 (lldb) process attach --pid 66098 Process 66098 stopped Executable module set to "/Applications/MacPorts/KF5/krunner.app/Contents/MacOS/krunner".
