I've left notebook yesterday with this hang for all night. The connection was stable. It looks, that after several hours steam has failed with:
Installing breakpad exception handler for appid(steam)/version(1405474565_client)

I've finally found the problem:
While steam tries to poll some audio information, pulseaudio hangs on eating something from it's cache.
symlink("/tmp/pulse-nWCGrRQCgnKs", "/home/puchuu/.pulse/c0baa1bfa21ba1cfa5c1067a000013d3-runtime.tmp") = -1 EEXIST (File exists)
rmdir("/tmp/pulse-nWCGrRQCgnKs") = 0
nanosleep({0, 10000000}, NULL) = 0
readlink("/home/puchuu/.pulse/c0baa1bfa21ba1cfa5c1067a000013d3-runtime", "/tmp/pulse-i6Y2qyhCmMf0", 99) = 23
lstat("/tmp/pulse-i6Y2qyhCmMf0", 0x7fff938983c0) = -1 ENOENT (No such file or directory)
umask(077) = 022
mkdir("/tmp/pulse-1oeOLfoot4Nm", 0700) = 0
umask(022) = 077
These lines were looped.
rm -rf ~/.pulse
rm -rf ~/.pulse-cookie
And all works fine. Please Valve, keep steam available without Lennart Poettering programs!
Nothing extracted yet.
I have installed steam on my notebook (amd e-350 & ati 6470M) and it doesn't want to start.
I was waiting for 30 minutes, no windows appears, than pressed Ctrl+C.
It looks impossible to be fixed without access to source code.
