Comment 0 for bug 1573553

To reproduce:
1. Open BleachBit
2. Select many cleaner (to produce a long list)
3. Click to the beginning of the text, scroll down with the scroll bar, [Shift]+click to the end of the text
    (Alternatively: right click to the text - > select all
4. The application will crash immediate.

When starting bleachbit from the terminal, the crash produces this message:

The program 'bleachbit' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 16528 error_code 3 request_code 18 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 --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.)
