Application: plasmashell (5.27.5) Qt Version: 5.15.8 Frameworks Version: 5.103.0 Operating System: Linux 6.1.0-9-amd64 x86_64 Windowing System: X11 Distribution: Debian GNU/Linux 12 (bookworm) DrKonqi: 5.27.5 [CoredumpBackend] -- Information about the crash: I had opened a terminal window and was navigating between tabs. I could see `cd <dir_name>` happening in the terminal. I wanted to check if typing `dolphin .` opens a new tab or new window. It opened a new window and I tried switching to the other one by cliking on the taskbar hover-preview. That's when it crashed. Suggestion: I think instead of opening a new window, a new tab could be opened in the same window (that might be a long shot technically so I don't know how much effort that takes; this is just a suggestion). The reporter is unsure if this crash is reproducible. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault PID: 2091 (plasmashell) UID: 1000 (vaibhav) GID: 1000 (vaibhav) Signal: 11 (SEGV) Timestamp: Tue 2023-07-04 07:57:27 IST (44s ago) Command Line: /usr/bin/plasmashell --no-respawn Executable: /usr/bin/plasmashell Control Group: /user.slice/user-1000.slice/user@1000.service/session.slice/plasma-plasmashell.service Unit: user@1000.service User Unit: plasma-plasmashell.service Slice: user-1000.slice Owner UID: 1000 (vaibhav) Boot ID: d2966535bc244ef783ff92d7504e0bbc Machine ID: 93e6cef4a1384fe694236f85a1a8ad60 Hostname: debian-amd64 Storage: /var/lib/systemd/coredump/core.plasmashell.1000.d2966535bc244ef783ff92d7504e0bbc.2091.1688437647000000.zst (present) Size on Disk: 48.0M Message: Process 2091 (plasmashell) of user 1000 dumped core.

A variation of the information provided already and a way to reliably reproduce the crash condition follows: 1) Using an Icons-only widget on a desktop panel (which may or may not be a required condition), run multiple instances of an app, e.g. Dolphin. 2) Hover over the icon shown on the Icons-only widget such that multiple mini-instances of the application appear 3) Move the mouse cursor over the [x] of one of the instance's (I always chose the instance to the right rather than to the left) 4) Simultaneously click both the left and the right mouse buttons over the [x], et voila! Crash.
