Loading the URL above gives:

###!!! ASSERTION: Queue and cache sizes out of sync!: 'queuesize == cachesize', file /Users/bzbarsky/mozilla/debug/mozilla/modules/libpr0n/src/imgLoader.cpp, line 494

In particular, we have:

(gdb) frame 5
#5  0x02d46ab3 in imgLoader::VerifyCacheSizes () at /Users/bzbarsky/mozilla/debug/mozilla/modules/libpr0n/src/imgLoader.cpp:494
494       NS_ASSERTION(queuesize == cachesize, "Queue and cache sizes out of sync!");
(gdb) p queuesize
$1 = 1
(gdb) p cachesize
$2 = 3
(gdb) p sCacheQueue.GetNumElements()
$3 = 1
(gdb) p sCache.Count()
$4 = 3
(gdb) p sChromeCacheQueue.GetNumElements()
$5 = 0
(gdb) p sChromeCache.Count()
$6 = 0

Sorry about the lack of minimal-ish testcase...
Probably related is:

WARNING: Expired objects were not removed or marked used: file ../../../dist/include/xpcom/nsExpirationTracker.h, line 215

This looks a lot like it's being caused by bug 89419 -- image requests think they have one URI, but actually have another, so they're removed from the queue on pop, but can't be found in the cache because they don't have the keyed URI.
Hmm.  There is indeed a 302 here for a gif (redirecting to http://ds.serving-sys.com/BurstingCachedScripts/Res/Blank_1x1.gif).  I get the assert a whole bunch, but that's because after the 302 every single image load (for the rest of the browsing session, even after I leave this page) asserts.

Can we at least do something about the latter? ;)
Or just fix bug 89419.

Bug 89419 is fixed, and thus so is this.
