I cannot reproduce this behavior; did you do anything different than these steps? Steps: 1. Right-click on the "Downloads" folder. 2. Click on "Properties" in the context menu. 3. Click on the icon button next to the file name. 4. The icon picker opens up correctly. Operating System: KDE neon Developer Edition KDE Plasma Version: 5.15.3 KDE Frameworks Version: 5.57.0 Qt Version: 5.12.0 This might also be a problem with KDE Frameworks 5.56.0 as the crash happens in KF5ItemViews. Sadly, I cannot find Frameworks 5.57.0 anywhere in the Arch repos...
Hi! I've tried to reproduce this issue as well, with no luck, on current neon user (5.55.0 frameworks, 5.15.3 plasma, 5.12 qt). I've played around with file permissions and so on, and it didn't help me reproduce it. Alex, could you please provide more information about your system? Is this behaviour specific to a given file? In case it is, please provide us some details about the file - xattrs, permissions Is this behaviour reproducible on more then one file, please try to narrow it down to a location - is it specific to a given filesystem? (Remote FS, local FS, local exact device?) Is this behaviour reproducible on clean profile? (run from a new user or something in that lines) In case you'll be able to reproduce the issue, please update the crash log after installing debug symbols for package that provides libKF5ItemViews.so.5 pacman -Fs /usr/lib/libKF5ItemViews.so.5 should provide you with the package name. Not sure how debug packages are distributed in Arch. #6 0x00007f8e187b9fd9 in ?? () from /usr/lib/libKF5ItemViews.so.5 #7 0x00007f8e187ba394 in ??

Looks like this is just a packaging issue then! As Julian says, it's likely the mismatch in frameworks versions. If the issue still occurs when pushed to stable repos I will report the bug downstream in the Arch bug trackers. Thank you
*** Bug 406293 has been marked as a duplicate of this bug. ***
@Antonio: can you reproduce this crash? Is it really downstream?
Yes, I can reproduce. It's certainly not downstream, and not reproducible with Qt 5.12 (so possibly a Qt issue) Full backtrace: #0 KListWidgetSearchLine::KListWidgetSearchLinePrivate::updateHiddenState (this=0x5555561ee880, start=<optimized out>, end=-1) at /usr/src/debug/kitemviews-5.56.0/src/klistwidgetsearchline.cpp:188 #1 0x00007ffff70395e6 in KListWidgetSearchLine::KListWidgetSearchLinePrivate::_k_dataChanged (this=<optimized out>, topLeft=..., bottomRight=...) at /usr/include/qt/QtCore/qabstractitemmodel.h:62 #2 0x00007ffff70396d4 in KListWidgetSearchLine::qt_static_metacall (_o=_o@entry=0x5555561f0910, _id=_id@entry=9, _a=_a@entry=0x7fffffffd9c0, _c=QMetaObject::InvokeMetaMethod) at /usr/src/debug/build/src/KF5ItemViews_autogen/include/moc_klistwidgetsearchline.cpp:121 #3 0x00007ffff70397d6 in KListWidgetSearchLine::qt_static_metacall (_o=_o@entry=0x5555561f0910, _c=_c@entry=QMetaObject::InvokeMetaMethod, _id=_id@entry=9, _a=_a@entry=0x7fffffffd9c0) at /usr/src/debug/build/src/KF5ItemViews_autogen/include/moc_klistwidgetsearchline.cpp:108 #4 0x00007ffff5d9053b in QMetaObject::activate (sender=sender@entry=0x5555561ed910, signalOffset=<optimized out>, local_signal_index=local_signal_index@entry=0, argv=argv@entry=0x7fffffffd9c0) at kernel/qobject.cpp:3801 #5 0x00007ffff5d907bf in QMetaObject::activate (sender=sender@entry=0x5555561ed910, m=m@entry=0x7ffff6022100 <QAbstractItemModel::staticMetaObject>, local_signal_index=local_signal_index@entry=0, argv=argv@entry=0x7fffffffd9c0) at kernel/qobject.cpp:3652 #6 0x00007ffff5d06dce in QAbstractItemModel::dataChanged (this=this@entry=0x5555561ed910, _t1=..., _t2=..., _t3=...) at .moc/moc_qabstractitemmodel.cpp:557 #7 0x00007ffff6b2fad3 in QListModel::itemChanged (this=this@entry=0x5555561ed910, item=item@entry=0x555555f9ac20, roles=...) at itemviews/qlistwidget.cpp:455 #8 0x00007ffff6b3096d in QListWidgetItem::setData (this=this@entry=0x555555f9ac20, role=<optimized out>, role@entry=0, value=...) at itemviews/qlistwidget.cpp:741 #9 0x00007ffff6b31c2c in QListWidgetItem::QListWidgetItem (this=0x555555f9ac20, icon=..., text=..., listview=<optimized out>, type=<optimized out>) at itemviews/qlistwidget.cpp:688 #10 0x00007ffff736f062 in ??
