But when cleaning up afterwards the git-svn script produces a segfault. STEPS TO REPRODUCE 1. Clone a git repository from an SVN server and set kwallet as password storage backed. 2. Run "git svn rebase" 3. Observe the crash OBSERVED RESULT Calling "git svn rebase" will now always generate a segfault: [ 6470.589903] git-svn[1291]: segfault at 7f25e8ab8f80 ip 00007f25e897a3e6 sp 00007ffd8c670d70 error 4 in libKF5CoreAddons.so.5.50.0[7f25e8972000+5e000] [ 6470.589908] Code: f8 ff 74 06 f0 83 2f 01 74 7a 48 8b 7b 08 8b 07 85 c0 0f 84 92 00 00 00 83 f8 ff 74 0a f0 83 2f 01 0f 84 25 02 00 00 48 8b 03 <8b> 10 85 d2 74 24 83 fa ff 74 06 f0 83 28 01 74 19 48 8b 7d 00 48 [ 6470.590013] audit: type=1701 audit(1536562099.754:82): auid=1000 uid=1000 gid=100 ses=6 pid=1291 comm="git-svn" exe="/usr/bin/perl" sig=11 res=1 Additional info on used Arch package versions: * git 2.21.0-1 * perl 5.28.2-1 * kcoreaddons 5.57.0-1 * kwallet 5.57.0-1 * qt5-base 5.12.3-2 ADDITIONAL INFORMATION Original Arch Linux Bug report: https://bugs.archlinux.org/task/60005 1855601 1 mpyne 2019-05-12 00:22:19 +0000 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. 1857771 2 cfeck 2019-05-21 18:42:08 +0000 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. 1858331 3 arojas 2019-05-23 20:19:54 +0000 (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. 1858771 4 arojas 2019-05-25 19:13:04 +0000 Also reproducible in Tumbleweed, so definitely not a downstream problem. 1873844 5 d.scheftelowitsch 2019-08-08 21:37:39 +0000 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 () 1876073 6 cfeck 2019-08-20 21:29:10 +0000 Which application is crashing?
