404 pages broken, possibly busting Fx3.0 debug builders

$ curl -I
 HTTP/1.1 500 Internal Server Error

Firefox just displays an empty page, but I think it causes problems to our debug builds of Fx3.0.x,

Windows builds from 2009/05/12 23:49 PDT (on WINNT 5.2 fxdbug-win32-tb Dep Debug + Leak Test), and Mac builds from 2009/05/13 00:10 PDT (on MacOSX Darwin 8.8.4 bm-xserve11 Dep Debug + Leak Test), hit an assertion:

###!!! ASSERTION: unexpected progress values: 'progress <= progressMax', file e:/builds/tinderbox/Fx-Trunk-Memtest/WINNT_5.2_Depend/mozilla/netwerk/protocol/http/src/nsHttpChannel.cpp, line 4587

while executing "firefox -P default" on a new profile. IIRC the browser is trying to load the whatsnew url in that situation. See

We can rule out code change on CVS (last was 2009/05/07) and the outage affecting the build machines (the windows box was off but mac is real hardware and hits this too). It's possible there is something odd in the server(s), but also CCing fantasai because her checking at 2009-05-12 15:01 to mozilla-org/html/404.html seems strongly related.
FWIW, we're not hitting this on Linux 3.0, or any platform for 3.5 or 3.6.
Depends on: 453475
Reed, fantasai: Why is that page a weird 404/500 mix after your work yesterday? lost its +x again. I added a temp fix... need to hack the tools to do it for me. Change is being synched out now.

Reed, do you want to reopen this to "Really Fix It (tm)" or handle elsewhere ?

New bug, please. I'll try to get to it within the next day or so.
