https://bugs.kde.org/show_bug.cgi?id=368560 --- Comment #2 from Kevin Funk --- This crash seems to be caused by the QML-based Welcome Page plugin (that's likely why you see KDevelop crashing, but not the other Qt-based apps): #14 0x7f50059154d0 in QQuickRenderControl::~QQuickRenderControl() () from /usr/lib/libQt5Quick.so.5 #15 0x7f5005e98143 in ??

() from /usr/lib/libQt5QuickWidgets.so.5 #18 0x7f50100b5547 in QObject::~QObject() () from /usr/lib/libQt5Core.so.5 #19 0x7f5010da4933 in QWidget::~QWidget() () from /usr/lib/libQt5Widgets.so.5 #20 0x7f4fd1b8627e in ?? () from /usr/lib/qt/plugins/kdevplatform/25/kdevwelcomepage.so This looks like an upstream issue in Qt, to debug further we'd need a valgrind run of KDevelop, to get more details about the crash. It'd be awesome if one of you guys could run KDevelop through valgrind and then try to reproduce the crash: valgrind --smc-check=all-non-file --track-origins=yes kdevelop &> out If you just want to work-around the problem for the time being, you could make KDevelop not load the Welcome Page plugin at all, by setting this environment variable: KDEV_DISABLE_WELCOMEPAGE=1 -- You are receiving this mail because: You are watching all bug changes.
