>Description:
Since my last update of ports yesterday, when closing one of multiple open tabs in firefox 3.5.9, the browser crashes with the following console message:

The program 'firefox-bin' received an X Window System error.
This probably reflects a bug in the program.
The error was 'RenderBadPicture (invalid Picture parameter)'.
  (Details: serial 123298 error_code 157 request_code 147 minor_code 7)
  (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.)

Interestingly, this seems to happen only if the tab has been open for more than a few seconds, but then the crash is quite repeatable.
>How-To-Repeat:
Open multiple tabs in firefox 3.5.9 (firefox-3.5.9,1), wait a while, then open one tab.
>Fix:
Downgrading cairo-1.8.10_1,1 to cairo-1.8.8_1,1 seems to have solved the problem.
