[Bug 371869] Re: Shiretoko 404'ing on pages which exist

[Ben Hodgens]

Here's something additional; I'm unsure if it's pertinent. I get a
segfault when running 'strace firefox-3.5' (it would appear that
shiretoko detatches from strace). This is new hardware, though I have
(mostly) verified its stability by running memtest86+ for a day.

Here's the backtrace of strace:

munmap(0x7f13a714f000, 4096)            = 0
