If this is indeed a duplicate, then bug 393528 is not fixed. 1754933 3 elvis.angelaccio 2018-05-26 13:42:18 +0000 Hmm, indeed. The stacktrace seems the same though, weird. 1756464 4 elvis.angelaccio 2018-06-03 10:55:48 +0000 So, on master we have dolphinmainwindowtest crashing with the very same backtrace, so this indeed is not bug #393528. The crash is caused by the lambda slot in PlacesItem::setUrl(). I'll push a patch that fixes the dolphinmainwindowtest crash and should hopefully also fix this crash. 1756471 5 elvis.angelaccio 2018-06-03 11:19:36 +0000 Git commit 588abbf1b6994245d987c0d07c2b074cb76fc034 by Elvis Angelaccio. Committed on 03/06/2018 at 11:08. Pushed by elvisangelaccio into branch 'Applications/18.04'. Fix crash in PlacesItem::setUrl() Connections to lambda slots without context/receiver argument can lead to crashes, because if the receiver is deleted Qt won't delete the connection as it normally would when the receiver is specified. This patch moves the slot from the lambda in PlacesItem (which is not a QObject) to PlacesItemSignalHandler. This fixes the `dolphinmainwindowtest` crash we currently have on master, and should also fix bug #394507 which has the very same stacktrace.
