We'll need more info to get farther. Can you put /tmp/dumps/crash_20140113142533_1.dmp somewhere downloadable?
My Steam is segfaulting on the same line but i'm on arch linux. Here are 2 log outputs (one without debugger and one with gdb), maybe they are useful to you.
we were discussing this Problem here (more info):
https://bbs.archlinux.org/viewtopic.php?id=174356
Without debugger:

That segfault is in the AMD video driver, so you'd want to pursue it with AMD.
@timeswind just a friendly heads-up that your issue report is not actionable without additional information and may be closed pending more details.
Hello @timeswind, if you're still experiencing this issue on an up to date system, we'll need to do a fresh investigation. Closing.
