We need to see the full backtrace with debug symbols to see what's going on. Please install the gdb package, and in the terminal run:
gdb budgie-control-center
At the first prompt, type r and hit the Enter key.
At the next prompt, type y and hit the Enter key to download all necessary debug symbols.
Once the crash occurs, in the prompt, type:
set logging enabled
set logging file path/to/file.log
bt full
This will redirect output to a file path of your choosing, and then display the full backtrace. Upload the contents of the log file to a service like pastebin.com, and post a link to it in this thread.
Once done, type q and hit the Enter key to quit the gdb program.
