When attempting to run Steam, it tries to update the client... And then, just crashes. Running it on a terminal gives off the following output:

I've managed to workaround by running the Windows version of Steam through Wine, but when I try to do that, it fails to download any game- Message: "Steam content servers unreachable"

Steps for reproducing this issue:

1. Install Mageia 6 (32 bit)
2. Install Nvidia drivers (420 or later)
3. Install Steam
4. Run Steam on a terminal
