Frequency
Always
Bug description
When I try to unmount a drive by clicking the unmount option in nemo, it crashes nemo instead of unmounting. The drive was mounted as /run/media/cyberknight/Cruzer so I ran lsof | grep /run/media/cyberknight/Cruzer and saw that mpv was playing a video from it. After killing MPV, nemo unmounts the drive perfectly fine. When running nemo from the terminal and reproducing it, this is the output:

I have attached the coredump file here: https://drive.google.com/file/d/1wPfPKoyw9YkZo2h062neS1961gqSK1SO/view?usp=sharing
I ran the coredump file through gdb via gdb /usr/bin/nemo l and ran bt full then got this:
