If any on the entries specified on the default applications existe on machine, kde-open5 triggers a loop on respawn the call, making impossible to stop, unless you replace a proper application on defaults or in some cases inhibit the access to kde-open5 binary. Reproducible: Always Steps to Reproduce: On system settings applications default: Change the browser app to anything non available Call on terminal: kde-open5 "http://www.google.com" Impossible to stop dialog without plcaing a proper browser binary on defaults. Change the mail service for something unavailable kde-open5 "mailto:somthing@kde.org" kmailservice5 tries to respawn kde5-open when not found the proper mail application Actual Results: Qt is returning a strange message: kioclient(18265)/(default) unknown: QCoreApplication::postEvent: Unexpected null receiver
I cannot reproduce here, both cases opened the expected application.
No, the badness happens when you set an application that doesn't exist.
I cannot reproduce this on kubuntu 15.04. KIO throws an error message saying: "Could not find the program 'foobar'" and "The file or folder http://www.google.com/ does not exist". Afterwards kde-open5 exits as expected. Apparently this has been fixed.
Can't reproduce the bugs with the instructions provided here (it falls back to firefox and kmail) but https://bugs.kde.org/show_bug.cgi?id=354151 says one should uninstall kmail first....
