Ok, i can reproduce the crash if i follow your steps. But this looks for me like a artificial situation which will never happens in real life normaly. Because you can remove the drawer without a crash if the drawer is open or the drawer isn't open. Only when you did step 3 in combination with step 4 the issue still exists. So why you leave the context menu open (step 3) when you want to remove the drawer later? Sorry, that sounds a bit weird. Feel free to open a issue report directly to upstream at github and inform the developers. https://github.com/mate-desktop/mate-panel/issues?state=open Good luck.
