Unable To Close MOC - Githubissues

Bug and expected behavior Unable To Close MOCP Client When MOC Server Is Running , it hangs forever and it doesn't close the window once it's detached .

No profile and disabling firejail When Using --noprofile same issue happens , when calling mocp with full path and detaching using q it closes normally tho the other window is still hanging.

Reproduce Steps to reproduce the behavior: Currently There's no way to reproduce this behavior except running mocp with no sandboxing .

[x] The profile (and redirect profile if exists) hasn't already been fixed upstream.
[x] The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
[x] I have performed a short search for similar issues (to avoid opening a duplicate).
[ ] If it is a AppImage, --profile=PROFILENAME is used to set the right profile.
