Scott: I don't know if this is truly a bug for you, but you know more than any one else about nsCOMPtr. So I'm starting with you. I'm getting an unhandled exception that gives the following message: "You can't dereference a NULL nsCOMPtr with operator->()." The error shows up at line 2379 in file, mozilla\layout\html\base\src\nsTextFrame.cpp I'm attaching a file of the call stack at error. To generate the bug, go to the test page URL. No magic needed. I noticed this bug after I fixed another bug that crashed us before this bug could do its stuff.

Scott: I'm reassigning this one back to me. I have a grip on it I think. This is in the code between the imglib and necko. I can run with it. -pn

While the descriptions sound wildly different, I believe this bug to be a dupe of 14227 and 14181 (reassigned to rpotts. Fix should be checked in). The unhandled exception, if continued, results in a crash. This crash is the same as the crash in 14227 and 14181. *** This bug has been marked as a duplicate of 14227 ***
