(geany:7948): Gdk-WARNING **: 11:39:56.739: The program 'geany' received an X Window System error. This probably reflects a bug in the program. The error was 'BadAccess (attempt to access private resource denied)'. (Details: serial 5385 error_code 10 request_code 104 (core protocol) minor_code 0) (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 GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)
