This probably reflects a bug in the program. The error was 'BadValue (integer parameter out of range for operation)'. (Details: serial 281 error_code 2 request_code 146 minor_code 5) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) aborting... Program received signal SIGTRAP, Trace/breakpoint trap.
