Confirmed with a local debug build of r20355.  This also appears to crash with any URL, not just Yahoo.

Here's the back trace from my debug build if it's any more help:

This looks to be caused by http://trac.webkit.org/projects/webkit/changeset/20182.  Even pasting a URL into the address bar once private browsing is turned on causes a crash.

[Brady Eidson]

Already in Radar as <rdar://problem/5073391>

The private browsing part seems to be key, and pretty much bumps this to P1 in the Radar as well.  I'll work on this asap

Just want to say I am flattered/honored to have discovered a real bug... this beta testing is all new to me. I am the founder of a web company... but usually I am the "can you make it do this?" idea behind the programming guy, not the programmer or tester (or as my IT guys says, it is his job to try and break what we build)

anyway, thanks!

[Brady Eidson]
