* SUMMARY
I've gotten an assertion failure twice so far in a debug build of WebKit r25488
with Safari 3 Public Beta v. 3.0.3 (522.12.1) on Mac OS X 10.4.10 (8R218). 
Haven't figured out how to reproduce it yet.  Happens when I click on a link
(apparently at the wrong time).

* CONSOLE

ASSERTION FAILED: iconID
(/path/to/WebKit/WebCore/loader/icon/IconDatabase.cpp:1898 void
WebCore::IconDatabase::removeIconFromSQLDatabase(const WebCore::String&))
Segmentation fault

* CRASH LOG

Exception:  EXC_BAD_ACCESS (0x0001)
Codes:      KERN_INVALID_ADDRESS (0x0001) at 0xbbadbeef
