woody e thunderbird

[faz <faz@chiozzi.it>]

Ciao
Ho installato su woody con kernel 2.4.19
da www.backports.org il thunderbird
ma quando lo lancio mi dice così:
-_________________________________________________________________________________________________________________
(mozilla-thunderbird-bin:448): Gdk-CRITICAL **: file gdkpixmap-x11.c: 
line 218 (
gdk_bitmap_create_from_data): assertion `window == NULL || GDK_IS_WINDOW 
(window
)' failed
The program 'mozilla-thunderbird-bin' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadPixmap (invalid Pixmap parameter)'.
 (Details: serial 2924 error_code 4 request_code 56 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.)
