[Users] Strange Claws Mail 3.8.0 window closing, under Kubuntu 12-04

[Laurent Bloch]

Hi,

Since I upgraded Kubuntu to 12-04, the Claws Mail (3.8.0) window
closes every time I send a message (or I close a message composition
window) with the following message :

The program 'claws-mail' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 148517 error_code 3 request_code 155 minor_code 3)
  (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.)

Any hint? Cheers.
