We're behind an authenticating proxy (MS-ISA Server, username including domain in 'domain\username' format). When loading a page after entering an URL, I supply my proxy username+password. After I press OK, Safari crashes. Intranet pages (in proxy skiplist) do display OK.

Thanks for the bug report, Doeke! I hope you removed your username/password (or changed it) in the packet dump of Attachment 15046 [details]. :) This bug is probably not in WebKit, and if so will eventually be closed as RESOLVED/INVALID. It needs a Radar bug filed for it (Apple's internal bug tracking tool). You may do that by using https://bugreport.apple.com/. If you don't have an ADC membership, you may create a free "online" membership on https://connect.apple.com/ to log in to bugreport and file a Radar. Please mention this Bugzilla bug in the Radar, and mention the Radar bug number (not the URL) back here. Thanks!
Safari crashed before sending my password. But thanks for the warning ;-)

This issue can't be fixed in WebKit (it's in a lower-level framework), thus closing this bug as RESOLVED/INVALID. The issue will be tracked by the Radar bug noted in Comment #4. Thanks for filing this bug!
