Backtrace from Konqueror (KDE) crash report

The application Konqueror crashes every time you try to connect to
www.asus.com. The bug was first reported to the kde project but they say its
not their problem and it should be reported to freedesktop and a bug in
nouveau. The backtrace is in the attached file.

--- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> ---
The relevant bit of the stacktrace:

#10 0x42834a87 in __assert_fail () from /lib/libc.so.6
#11 0xaf348070 in nouveau_scratch_init () from
/usr/lib/dri/nouveau_vieux_dri.so
#12 0xaf3436ed in nouveau_context_init () from
/usr/lib/dri/nouveau_vieux_dri.so
#13 0xaf34d811 in nv10_context_create () from /usr/lib/dri/nouveau_vieux_dri.so
#14 0xaf343abd in nouveau_context_create () from
/usr/lib/dri/nouveau_vieux_dri.so
#15 0xaf36045f in dri2CreateContextAttribs () from
/usr/lib/dri/nouveau_vieux_dri.so
#16 0xaf360638 in dri2CreateNewContext () from
/usr/lib/dri/nouveau_vieux_dri.so
#17 0xb4032024 in dri2_create_context () from /lib/libGL.so.1
#18 0xb400824a in CreateContext () from /lib/libGL.so.1
#19 0xb4008541 in glXCreateContext () from /lib/libGL.so.1

And the code in nouveau_scratch_init:

    for (i = 0; i < NOUVEAU_SCRATCH_COUNT; i++) {
        ret = nouveau_bo_new(context_dev(ctx), NOUVEAU_BO_GART |
                     NOUVEAU_BO_MAP, 0, NOUVEAU_SCRATCH_SIZE,
                     NULL, &scratch->bo[i]);
        assert(!ret);

Looks like it's trying to get 2 3MB bo's, but it can't.
Unfortunately error
handling is often done rather poorly in the nouveau_vieux driver (via asserts
rather than returning error codes).

What card are you using? How much VRAM does it have? What resolution are you
running your screen at? What kernel are you on? What version of
xf86-video-nouveau and mesa are you using?

Oh, and another relevant question -- what is the GART size? Actually, just
attach your dmesg, that should answer a bunch of questions. (Would still want
to know versions of the various things I mentioned in the previous comment.)

--- Comment #6 from Ilia Mirkin <imirkin at alum.mit.edu> ---
OK, well it seems like eventually you start getting allocation errors. This
could mean that we're somehow leaking video memory, or just not using it
wisely, or that there's just not enough to go 'round. Modern
applications will
want a lot more 3d than this card can provide anyways... unless you plan on
using it for 3d activities, you could set LIBGL_ALWAYS_SOFTWARE=1 somewhere in
your environment which will cause mesa to fall back on llvmpipe or swrast.

Another possibility is that you're being bitten by the libdrm bug that was
exposed by gcc-4.8 (which I see your kernel is compiled with). Try a libdrm
with commit
http://cgit.freedesktop.org/mesa/drm/commit/?id=482abbfafb56cbceaf5355c026434e638cddd0f1
applied and see if it helps.
