Crash with X Window System error

[Schwarzburg]

The output is:

The program 'xournal' received an X Window System error.
This probably reflects a bug in the program.
The error was 'XI_BadClass (invalid Class parameter)'.
  (Details: serial 15498 error_code 153 request_code 141 minor_code 6)
  (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.)

xournal version 0.4.5
Ubuntu 11.04

If this happened after unplugging an input device (external mouse or tablet e.g.) while xournal was running, this problem has been fixed in newer upstream releases. -- Denis
