Bug 17379 – Crash in CoreFoundation loading ftp content

• Component: Page Loading
• Status: RESOLVED INVALID

[mikie]

i experience crash of safari on each loading of the page (Leopard 10.5.2 + WebKit r30267).
some people reported safari problems related to this page under windows too.

Confirmed, but it appears to be crashing in code outside of WebKit:

Exception Type:  EXC_BAD_ACCESS (SIGBUS)
