I've been doing some tests also and managed to crash safari and firefox with java content pages. I've never noticed this before but it's there. Also the crash report seems to point to the dyld located in /usr/lib.
I've been posting some crash logs into Andy's thread related to this dyld and he was going to take a look at the problem. Now I'll post this in voodoo's thread but I have little hope to get a solution cause they're busy helping chameleon's team, but let's hope the best.
