[Openmcl-devel] Webkit issue

Under ccl-64 intel, if I do:

(require 'webkit)
  and  then use ccl::browser-window to load a static web page,  
everything is fine.

However, if I use ccl::browser-window to load anything more complex  
(e.g., the Apple home page) then I consistently get the following crash.

Possibly this is because Safari knows how to talk to server versions  
of browser plug-ins that are still only 32-bit (e.g., QuickTime 7) and  
ccl-64 doesn't? Just a wild guess.

FWIW, the equivalent is not an issue under either ccl-32 intel or  
LWM-64 intel 5.1.2.

Should I open a ticket on this?

warmest regards,
