Gnome proposing to quit the app

All my Source engine games (Team Fortress 2, Left 4 Dead 2, Half-Life²,
Counter-Strike: Source) doesn't work anymore since commit:

commit: 70cf6639c331342619e65c46db925d115bf51920
gallium/radeon: create and return a fence in the flush function

Reviewed-by: Christian König <christian.koenig at amd.com>

Since this commit, when I launch one of this game, the screen stays black or it
will not launch at all. Finally I got a message from Gnome proposing to wait or
quit the app (cf. screenshot).

Config:
kernel 3.13.9-100.fc19.x86_64
libdrm 2.4.53-1.fc20

AMD Evergreen (Radeon HD 5850)
OpenGL renderer string: Gallium 0.4 on AMD CYPRESS

Build config:
autogen.sh --with-gallium-drivers=r600 --with-dri-drivers=
--enable-texture-float --disable-dri3 --disable-r600-llvm-compiler
--disable-gallium-llvm --enable-32-bit CFLAGS="-O2 -m32" CXXFLAGS="-O2 -m32"
--libdir=/usr/lib
