This happened before the 3/26 update and continued to happen after the emergency hotfix.
The console command '/UseDevice Devices n' (n=0,..3) used to activate items in the ship or character device slots - it made for a great set of keybinds. This week it stopped working (in space, at least). The keybinds stopped working and the command didn't work from the chat window either.
When I typed '/cmdlist' into the chat window to check spelling & arguments, etc., the game client instantly vanished. I got as far as typing '/cmdlist' into the bug report dialog box, and the dialog box vanished too...
I noticed a similar bug last night. Running the command "/cmds map" crashes the client. I tested it twice myself, and had two of my friends test it. It seems to happen pretty reliably.

/UseDevice worked before DR at least.
