Moin moin I can confirm the crash. mfg Tobias
I get a fairly consistent bt like this ``` (lldb) bt * thread #1, name = 'spectacle', stop reason = signal SIGBUS: hardware error * frame #0: 0x000000080246f67f libQt5Core.so.5`QObjectPrivate::connectImpl(QObject const*, int, QObject const*, void**, QtPrivate::QSlotObjectBase*, Qt::ConnectionType, int const*, QMetaObject const*) + 735 frame #1: 0x000000080246f287 libQt5Core.so.5`QObject::connectImpl(QObject const*, void**, QObject const*, void**, QtPrivate::QSlotObjectBase*, Qt::ConnectionType, int const*, QMetaObject const*) + 295 frame #2: 0x000000080d9455a2 libKF5kipiplugins.so.5.9.1`KIPIPlugins::KPImagesList::KPImagesList(QWidget*, int) + 3330 frame #3: 0x000000081908bac3 kipiplugin_remotestorage.so`___lldb_unnamed_symbol106$$kipiplugin_remotestorage.so + 675 frame #4: 0x0000000819088535 kipiplugin_remotestorage.so`___lldb_unnamed_symbol46$$kipiplugin_remotestorage.so + 101 frame #5: 0x00000008190880c5 kipiplugin_remotestorage.so`___lldb_unnamed_symbol38$$kipiplugin_remotestorage.so + 293 frame #6: 0x0000000802472b39 libQt5Core.so.5`___lldb_unnamed_symbol2439$$libQt5Core.so.5 + 1449 frame #7: 0x0000000801292dfa libQt5Widgets.so.5`QAction::activate(QAction::ActionEvent) + 314 frame #8: 0x000000080141557d libQt5Widgets.so.5`___lldb_unnamed_symbol1982$$libQt5Widgets.so.5 + 77 frame #9: 0x0000000801412aab libQt5Widgets.so.5`___lldb_unnamed_symbol1958$$libQt5Widgets.so.5 + 555 frame #10: 0x0000000801419e60 libQt5Widgets.so.5`QMenu::mouseReleaseEvent(QMouseEvent*) + 704 ``` which carries on from where Graham's bt trails off (I think in mouseReleaseEvent). Just seeing that there's dynamic_cast<> in the code makes me think I can guess a reason (there was a similar problem in kleopatra).
FWIW, I can also trigger the crash consistently with Export to Imageshack, again with a SIGBUS, so I think something **else** is messing up memory.
Slightly more detailed bt ``` Thread 1 received signal SIGSEGV, Segmentation fault. 0x00000008002f50f6 in KIPI::PluginLoader::interface (this=0x804f27be0) at /zbigone/src/kde/invent/libkipi/src/pluginloader.cpp:382 382 return d->interface; (gdb) bt #0 0x00000008002f50f6 in KIPI::PluginLoader::interface() const (this=0x804f27be0) at /zbigone/src/kde/invent/libkipi/src/pluginloader.cpp:382 #1 0x000000080e5bd610 in KIPIPlugins::KPDialogBase::Private::Private() (this=0x804fb9100) at /zbigone/src/kde/invent/kipi-plugins/common/libkipiplugins/dialogs/kptooldialog.cpp:66 #2 KIPIPlugins::KPDialogBase::KPDialogBase(QDialog*) (this=0x807401fd0, dlg=0x807401fa0) at /zbigone/src/kde/invent/kipi-plugins/common/libkipiplugins/dialogs/kptooldialog.cpp:78 #3 KIPIPlugins::KPToolDialog::KPToolDialog(QWidget*) (this=0x807401fa0, parent=<optimized out>) at /zbigone/src/kde/invent/kipi-plugins/common/libkipiplugins/dialogs/kptooldialog.cpp:163 #4 0x0000000820f0139f in KIPIImageshackPlugin::ImageshackWindow::ImageshackWindow(QWidget*, KIPIImageshackPlugin::Imageshack*) (this=0x807401fa0, parent=0x804ad4090, imghack=0x8092cb8e0) at /zbigone/src/kde/invent/kipi-plugins/imageshack/imageshackwindow.cpp:75 #5 0x0000000820efd1df in KIPIImageshackPlugin::Plugin_Imageshack::slotExport() (this=0x8092cad40) at /zbigone/src/kde/invent/kipi-plugins/imageshack/plugin_imageshack.cpp:118 #6 0x0000000802672b59 in () at /usr/local/lib/qt5/libQt5Core.so.5 #7 0x0000000801692dfa in QAction::activate(QAction::ActionEvent) () at /usr/local/lib/qt5/libQt5Widgets.so.5 ``` This particular crash is with kderc-build built spectacle on frameworks main, whatever that is today.
