Using master & Qt 5.10 (alpha then beta) akregator produces a core file for most feeds each time it tries to fetch articles. Core was generated by `http.so [kdeinit5] http local:/run/user/1000/klauncherErrRgF.1'.

Bisecting in akregator and kio didn't help. Looks like a change in Qt 5.10 is causing this. David ?
mouseover on failing feeds says 'Feed file not found on remote server' (from akregator's subscriptionlistmodel.cpp) which according to the syndication doc means "the host was contacted successfully, but reported a 404 error" (syndication/global.h). pasting the url in Firefox or konqueror works however (eg http://planetKDE.org/rss20.xml)
kio's output: tHost: Hostname is now: "planetkde.org" ( "planetkde.org" ) 15:06:32 - kio_http(20804) - kf5.kio.kio_http: HTTPProtocol::get: QUrl("http://planetkde.org/rss20.xml") 15:06:32 - kio_http(20804) -
