I wanted to get the new Partition Manager icon so badly that I downloaded it from gitlab, and went to the specified path: /usr/share/icons/breeze/apps/48/ which I needed to open in admin mode to be able to paste the icon there. Less than 30 seconds after pasting it, RAM usage skyrocketed and computer froze. STEPS TO REPRODUCE 1. Right click a file and select "copy" (you can try with a svg icon, like I did) 2. Open a protected path like /usr/share/icons/ 3. Right click in an empty space and select open as administrator 4. Paste the icon/file, you will be prompted to put your password 5. As soon as the copy operation finishes, memory usage starts to skyrocked leading to a computer lockup OBSERVED RESULT Computer totally frozen because the system runs out of RAM EXPECTED RESULT It shouldn't leak memory so much and so fast.

Git commit ae4af4ab84588f1d64149ba05d83bcb39fe84f7a by Harald Sitter. Committed on 22/04/2023 at 14:53. Pushed by meven into branch 'master'. delete threaded workers on a thread this prevents potential deadlocks between the worker thread and the main thread in case the former relies on the latter to do work. specifically qdbus seems unhappy if we wait in the main thread. in point of fact we shouldn't be waiting in the main thread anyway since the result of the thread is immaterial (wait is also called inside the workerthread destructor, I'm leaving it there as a safe guard against deleting still-running threads) M +14 -0 src/core/worker.cpp https://invent.kde.org/frameworks/kio/commit/ae4af4ab84588f1d64149ba05d83bcb39fe84f7a
