I suspect some kind of race condition during shutdown, where the global-static tries to delete an already-deleted KAboutData in the registry. I'm having trouble reproducing but I also don't have git-svn setup for kwallet. Based on the platform plugin message I've tried various settings of the environment variable QT_QPA_PLATFORM (xcb, minimal, eglfs) but that hasn't helped me reproduce either. The problem certainly isn't in KAboutData. The issue is that something calls exit(); the "org.kde.kwindowsystem: Could not find any platform plugin" message might be related. I suggest to report this issue to the bug tracker of your distribution. (In reply to Christoph Feck from comment #2) > I suggest to report this issue to the bug tracker of your distribution. This has gone throught downstream already. I have no idea what we are supposed to do about this TBH, this is reproducible in a plain Plasma session with unmodified KDE and svn packages. You just need a very specific setup to reproduce it. Also reproducible in Tumbleweed, so definitely not a downstream problem. I second reproducibility in Tumbleweed, with the following backtrace: #0 0x00007ffff659061c in std::__atomic_base<int>::load (__m=std::memory_order_relaxed, this=0x7ffff73a81c0) at /usr/include/qt5/QtCore/qrefcount.h:65 #1 QAtomicOps<int>::load<int> (_q_value=...) at /usr/include/qt5/QtCore/qatomic_cxx11.h:227 #2 QBasicAtomicInteger<int>::load (this=0x7ffff73a81c0) at /usr/include/qt5/QtCore/qbasicatomic.h:103 #3 QtPrivate::RefCount::deref (this=0x7ffff73a81c0) at /usr/include/qt5/QtCore/qrefcount.h:66 #4 QString::~QString (this=<optimized out>, this=<optimized out>) at /usr/include/qt5/QtCore/qstring.h:1133 #5 KAboutData::Private::~Private (this=<optimized out>, this=<optimized out>) at /usr/src/debug/kcoreaddons-5.60.0-1.1.x86_64/src/lib/kaboutdata.cpp:460 #6 KAboutData::~KAboutData (this=<optimized out>, this=<optimized out>) at /usr/src/debug/kcoreaddons-5.60.0-1.1.x86_64/src/lib/kaboutdata.cpp:581 #7 0x00007ffff65908cd in (anonymous namespace)::Q_QGS_s_registry::innerFunction()::Holder::~Holder() () at /usr/src/debug/kcoreaddons-5.60.0-1.1.x86_64/src/lib/kaboutdata.cpp:1033 #8 0x00007ffff7c69500 in __run_exit_handlers () from /lib64/libc.so.6 #9 0x00007ffff7c6963c in exit () from /lib64/libc.so.6 #10 0x000055555558c446 in main () Which application is crashing?
