Thanks for sending those in, by the way!  They make it much easier for 
us to track down and fix bugs.

Interesting!  So OmniWeb is crashing due to some transient system state 
that gets cleared up when you reboot.

I just looked at the crash report you sent right before sending this 
message, and  the backtrace for the crash is:

0 -- 0x99bb74d0 -- _ComputeIndex4__FPCUsUs
1 -- 0x99bb72c0 -- _MapString4_16__FPCUsn1UlPUsPc

11 -- 0x45b736b0 -- +[NSFont _fontWithName:size:matrix:]
12 -- 0x45c17bf0 -- +[NSFont fontWithName:matrix:]

In other words, OmniWeb is crashing when it tries to initialize a font, 
so you seem to be managing to get Quartz into a state where that fails 
(crashing OmniWeb).

You might be able to reset Quartz without a complete reboot, though not, 
of course, without breaking every other application's connection to the 
graphics server.  Try logging out and back in, or if that doesn't work 
try logging out, log in with the name ">exit", wait for the login window 
to reappear, then log in again.  (But if neither of those work, then 
perhaps rebooting is all you can do.)

Thanks for the crash reports and the detailed information about them!  
(The other thing you might want to do is to report this bug to Apple!)
