Created attachment 170019 [details] Crash dump without debug symbols regarding plasmashell clipboard SUMMARY Using KDE Plasma 6.1 Beta on Wayland, plasmashell would 'occasionally' crash on me. Took me a while to investigate to find out it's the clipboard component that's crashing and is remedied by undoing tweaks. X11 not affected. STEPS TO REPRODUCE 1. Use KDE Plasma Wayland. 2. Open Clipboard Configuration. 3. Enable [Keep the selection and clipboard the same] from "Selection and Clipboard"; & select [Always save in history] for "Text selection". 4. Run `plasmawindowed org.kde.plasma.clipboard` as this weirdly guarantees the crash for me if plasmashell doesn't. 5. Rapidly select text from any source. Repeat until crash either immediately or a few seconds after. OBSERVED RESULT Plasmashell with Wayland freezes and creates a crash dump which clues to clipboard involvement. Plasmawindowed also prints out a line of code that reportedly failed. EXPECTED RESULT No crashes and oddities. SOFTWARE/OS VERSIONS Operating System: EndeavourOS / Arch Linux KDE Gear Version: 24.05.0-1 KDE Plasma Version: 6.0.90-1 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.1 Kernel Version: 6.9.2-arch1-1 Graphics Platform: Wayland ADDITIONAL INFORMATION Currently using both 'kde-unstable' and 'extra-testing' Arch repo for Plasma 6.1 Beta. Reproducing the crash on X11 does not work which may mean only Wayland is affected. Attached DrKonqi report, but without debug symbols as it stresses my low-end system and fails. Unsure if this is related to bug 469663, but this does not involve URLs and pop-up menus. Lastly, the printed line upon interacting with the clipboard launched with `plasmawindowed`: ``` kf.plasma.quick: Applet preload policy set to 1 qml: 0 DataControlOffer: timeout reading from pipe DataControlOffer: timeout reading from pipe /usr/include/c++/14.1.1/bits/shared_ptr_base.h:1350: std::__shared_ptr_access<_Tp, _Lp, <anonymous>, <anonymous> >::element_type& std::__shared_ptr_access<_Tp, _Lp, <anonymous>, <anonymous> >::operator*() const [with _Tp = HistoryItem; __gnu_cxx::_Lock_policy _Lp = __gnu_cxx::_S_atomic; bool <anonymous> = false; bool <anonymous> = false; element_type = HistoryItem]: Assertion '_M_get() != nullptr' failed. Aborted (core dumped) ```
I can reproduce it in xorg too. Operating System: Arch Linux KDE Plasma Version: 6.0.90 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.1
it was happening to me after copying code generated by chatgpt from firefox. regular texts don't seem to generate this crash. And copying exactly the same code via chromium was no problem at all I don't know if this log is of any use, but here it is: https://pastebin.com/7t2N11u3 And the code I copied from firefox: https://pastebin.com/qdcPAPFs
Created attachment 170062 [details] X11 Crash attempt with debug symbols with Lorem Ipsum test
Tried to see if regular text causes a crash with the "Lorem ipsum" page on the Internet and on a text file opened with Kate. Also tried to give Xorg/X11 another shot along with my usual Wayland session. Tried to test with Firefox, Kate, and Konsole. So far, I have no definitive find on whether apps matter as I inconsistently crash with each of them with or without clearing history. Additionally, am unable to know what character or phrase breaks the clipboard. Spaces, alphabet, and newlines seems to crash it. I am unsure if copy length does anything, but was able to crash with seemingly empty entries and two newlines entries. However, I was able to do additional crashes. On Wayland, I could easily produce one frequently and had to clear history to prevent perpetual crashing (though, am unable to easily reproduce perpetual crashes). For X11, I have difficulty creating one, but I have done a crash and captured logs via gdb with debug symbols for `plasmashell` with `plasmawindowed` running org.kde.plasma.clipboard. The file has been attached just before this comment.
I apologize if I'm posting too frequently in a short timespan. I forgot to include that when I cannot cause an immediate crash for some circumstances, this printed line frequently pops up upon interacting with the clipboard window: ``` file:///usr/share/plasma/plasmoids/org.kde.plasma.clipboard/contents/ui/TextItemDelegate.qml:20: TypeError: Cannot read property 'slice' of undefined ``` That should be most of I can find at this time and am unsure if I can investigate this differently other than generating more logs.
