I haven't had time to reduce the test case, but I get a consistent crash dereferencing a null mChannel in nsHTTPServerListener::OnDataAvailable when viewing this page. It is opening up a link in a new window: <li><a href="mydomain/domain-info?domainid=53939" target="_new">pollmann.com</a> Here's a simple bullet-proofing fix: Index: nsHTTPResponseListener.cpp =================================================================== RCS file: /cvsroot/mozilla/netwerk/protocol/http/src/nsHTTPResponseListener.cpp,v retrieving revision 1.129 diff -u -r1.129 nsHTTPResponseListener.cpp --- nsHTTPResponseListener.cpp 2000/09/05 21:22:33 1.129 +++ nsHTTPResponseListener.cpp 2000/09/13 18:53:10 @@ -464,6 +464,7 @@ if (NS_SUCCEEDED(rv) && i_Length) { PRBool bApplyConversion = PR_TRUE; + if (!mChannel) return NS_ERROR_FAILURE; (void) (mChannel->GetApplyConversion(&bApplyConversion)); if (bApplyConversion && !mCompressHeaderChecked)

Cool! This is a common crash now and I had the same fix already (not checked in as yet though) Thanks for hunting it down. See bug 52397 *** This bug has been marked as a duplicate of 52397 ***
