Created attachment 117733 [details] New crash information added by DrKonqi plasma-discover (5.14.5) using Qt 5.11.2 - What I was doing when the application crashed: I was trying to install the lattest KDE Neon updates as of 01-30-2019. Discover crashes every time I try to install updates or start the discover interface. This has been happening for about a week. I restored the entire system back to a date of 12-31-2018 and discover worked without crashing. Once I installed all the updates to bring KDE Neon up to date as of 01-30-2019 discover started crashing again. I have KDE Neon installed on 3 different computers and this is the only one where discover crashes. Some sofware change since 12-31-2019 and my hardware is now causing discover to crash everytime. Let me know if you need more details. -- Backtrace (Reduced): #6 0x00007f096bf76d62 in AbstractResource::reportNewState (this=0x55bfbc60c450) at ./libdiscover/resources/AbstractResource.cpp:143 #7 0x00007f0968ed318f in QtPrivate::QSlotObjectBase::call (a=0x7fff4a4470b0, r=0x55bfbc60c450, this=0x7f0914016190) at ../../include/QtCore/../../src/corelib/kernel/qobjectdefs_impl.h:376 [...] #10 0x00007f096bf87cf3 in AbstractResource::stateChanged (this=this@entry=0x55bfbc60c450) at ./obj-x86_64-linux-gnu/libdiscover/DiscoverCommon_autogen/3YJK5W5UP7/moc_AbstractResource.cpp:430 #11 0x00007f0922bf2a2d in FwupdResource::setState (this=this@entry=0x55bfbc60c450, state=state@entry=AbstractResource::Upgradeable) at ./libdiscover/backends/FwupdBackend/FwupdResource.cpp:141 #12 0x00007f0922bf7cb5 in FwupdBackend::createApp (this=this@entry=0x55bfbc6a4c00, device=device@entry=0x7f09140046c0) at ./libdiscover/backends/FwupdBackend/FwupdBackend.cpp:235
