I'm also having this issue, I have a radeon HD 4550, and I am on linux mint 17 x64 this is the exact error:

And this is my glxinfo | grep OpenGL output:

And here's my sudo lshw -C video output:

EDIT:
So I just updated to newer drivers with the oibaf PPA with following process:
sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt-get update
sudo apt-get dist-upgrade
Which all completed successfully, now my glxinfo | grep OpenGL output is as follows:
Code:

But still it doesn't launch and I get the same error. If I missed a step or similar i'm open to trying other things to make this work.
