The core file is too large to be uploaded here, I uploaded it to Google Drive: https://drive.google.com/file/d/1o5_k5Csghpum-oB5hmuEtpb4EZ5HH7Mw/view?usp=sharing Thanks but we don't need the whole core. Can you use it to get a text backtrace? That would be helpful, especially if you can get it with debug symbols too for Plasma and Kirigami. (In reply to Nate Graham from comment #2) > Thanks but we don't need the whole core. Can you use it to get a text > backtrace? That would be helpful, especially if you can get it with debug > symbols too for Plasma and Kirigami. I have rebuilt the plasma-workspace and kirigami2 packages with debug symbols, replicating the issue resulted in this backtrace: (gdb) backtrace #0 0x00007f565e2369b8 in QtQml::qmlAttachedPropertiesObject(QObject*, QObject* (*)(QObject*), bool) () at /usr/lib/libQt5Qml.so.5 #1 0x00007f563230739f in qmlAttachedPropertiesObject<Kirigami::PlatformTheme>(QObject const*, bool) (obj=<optimized out>, create=<optimized out>) at /usr/include/qt/QtQml/qqml.h:703 #2 0x00007f5632300bc7 in ImageColors::postProcess(ImageData&) const (this=this@entry=0x55aaf5d875d0, imageData=...) at /usr/src/debug/kirigami2/kirigami2-5.101.0/src/imagecolors.cpp:450 #3 0x00007f56323045ad in ImageColors::generatePalette(QImage const&) const (this=0x55aaf5d875d0, sourceImage=<optimized out>) at /usr/src/debug/kirigami2/kirigami2-5.101.0/src/imagecolors.cpp:436 #4 0x00007f5632308fab in operator() (__closure=0x55aaf5ebe170) at /usr/src/debug/kirigami2/kirigami2-5.101.0/src/imagecolors.cpp:181 #5 QtConcurrent::StoredFunctorCall0<ImageData, ImageColors::update()::<lambda()>::<lambda()> >::runFunctor (this=0x55aaf5ebe0d0) at /usr/include/qt/QtConcurrent/qtconcurrentstoredfunctioncall.h:60 #6 QtConcurrent::RunFunctionTask<ImageData>::run() (this=0x55aaf5ebe0d0) at /usr/include/qt/QtConcurrent/qtconcurrentrunbase.h:108 #7 0x00007f565cae8241 in () at /usr/lib/libQt5Core.so.5 #8 0x00007f565cae431a in () at /usr/lib/libQt5Core.so.5 #9 0x00007f565c49f8fd in () at /usr/lib/libc.so.6 #10 0x00007f565c521a60 in () at /usr/lib/libc.so.6 Let me know if there's any other info you need!
