mozilla-[firefox|thunderbird]: "'firefox-bin' received an X Window System error" und "BadPixmap (invalid Pixmap parameter)"-Fehlermeldungen bei backports

[Heiko Heil <heiko.heil@gmx.de>]

Hallo Debian-User,

die beiden einzigsten backports, die ich unter meinem Woody-System
verwende, sind:

  mozilla-firefox 0.9.1-3.backports.org.1
  mozilla-thunderbird 0.6-1.backports.org.1

Nun beobachte ich folgende Abstürze (thunderbird stürzt mit der gleichen
Fehlermeldung ab), sobald ich unter firefox z.B. Edit / Preferences / Advanced
(reproduzierbar) aufrufe:

  $ mozilla-firefox
  [...]
  (firefox-bin:17051): Gdk-CRITICAL **: file gdkpixmap-x11.c: line 218 (gdk_bitmap_create_from_data): assertion `window == NULL || GDK_IS_WINDOW (window)' failed
  
  (firefox-bin:17051): Gdk-CRITICAL **: file gdkpixmap-x11.c: line 218 (gdk_bitmap_create_from_data): assertion `window == NULL || GDK_IS_WINDOW (window)' failed
  
  (firefox-bin:17051): Gdk-CRITICAL **: file gdkpixmap-x11.c: line 218 (gdk_bitmap_create_from_data): assertion `window == NULL || GDK_IS_WINDOW (window)' failed
  The program 'firefox-bin' received an X Window System error.
  This probably reflects a bug in the program.
  The error was 'BadPixmap (invalid Pixmap parameter)'.
    (Details: serial 6421 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.)

Das Interessante an der Sache ist, dass diese Abstürze nur unter *KDE2*
(Standard-KDE in Woody) auftreten. In *icewm* konnte ich dieses Verhalten
nicht feststellen.

Dieses Verhalten beobachte ich bei firefox erst nach meinem heutigen Update auf
0.9.1-3 (von 0.8) -- bei thunderbird schon seit einer ganzen Weile (ab
0.6).

Output von strace:

Meine .firefox-configs habe ich auch schon mal weggeschrieben - hat
nichts genutzt.

Über Hinweise und Tipps zu diesem Thema würde ich mich sehr freuen.

Danke...
