Kernel log from boot to error on nv25

I am running nouveau git kernel 3.4.0-rc2-g965a47f, xf86-video-nouveau ver.
fb3a36b and xorg-server 1.12.0 on nv25 card and I am getting PGRAPH erros

nouveau 0000:01:00.0: PGRAPH - ERROR nsource: LIMIT_COLOR nstatus:
PROTECTION_FAULT
nouveau 0000:01:00.0: PGRAPH - ch 1/4 class 0x009f mthd 0x0308 data 0x00240771

X then freezes but ssh or SysRq works. Additionally some icons on Gnome 3
fall-back mode have white rectangle in background instead of being transparent.
Didn't happen before libdrm rewrite.
Fastest way to reproduce seems to be right clicking to open pop-up menu or
opening drop-down selections - error happens in a few attempts.
On nv11 it seems not to crash, but some icons still have white background.
