Steam client crashes when running under Linux (locale problem)

My prefered platform for running Steam is Arch Linux at the moment. I have to start steam using the following command:

[user@host ~]$ LC_ALL=C steam

Otherwise I get a segmentation fault:

[user@host ~]$ steam

The problem is that not all locales supported by the host system are also supported by X (also see Valve GitHub Issue 1420). And a quick fix is to run LC_ALL=C steam.

It really took some time for me to figure this out. The problem is that the console output of the program does not give any hints about the cause of the segmentaton fault. Using Google did not help either because most Steam client crash reports out there do not have anything to do with system locale settings. I also tried to get to the root cause of the problem using tools like strace.

In the end I just had luck and found Valve GitHub Issue 1420 while browsing through Valves issue list for the Linux Steam client over at GitHub. This issue contained the information I needed to understand and finally run the Linux Steam client on my Arch Linux system.

My Steam client currently contains the following versioning information:
  • Built: Jul 8 2016, at 21:44:35
  • Steam package versions: 1468023329
Now I have to get back to kick some zombie ass :-) Dead Island: Definitvie Edition has been release on Linux a few weeks ago...
