Comment 51 for bug 286119

Either this bug is not related to samba or their are multiple unrelated bugs. On my amd64 box with kubuntu (all latest updates applied) firefox reliably crashes on this page:

http://code.google.com/android/reference/adb.html
Click on "Issuing ADB commands" crashes firefox and the following is printed on the console.

$ firefox
QPixmap: Invalid pixmap parameters
The program 'firefox' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 38913 error_code 11 request_code 53 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.)

As you can see it crashes in Qt/X11. And it seems to me there is an issue with the widget theme you are using in kde4? I am trying to find a widget set that works. but so far I am unable to verify if my conjecture is correct.
