This bug occurs in Webkit, but is exposed in Quartz Composer when downloading XML or RSS feeds which use NTLM authentication. Ports are opened to the webserver, and memory is allocated but is never properly closed, eventually crashing Quartz Composer.
What makes you think there is a memory leak? Does "leaks" report memory as being leaked, or does memory usage just increase? NTLM authentication isn't handle by WebKit, so this probably isn't the right place for this bug report.
