We're having a problem now whereby launching Spiral Knights from the Steam client results in it crashing at the login screen. Sometimes it reaches the character selection screen before crashing.
The odd thing is that yesterday, Spiral Knights from Steam worked just fine on the same computer. Nothing was changed that I think would break it.
The crash report, hs_err_pid5032.log, is here: https://gist.github.com/anonymous/84c65cd94be5c698749f
Edit: I updated the graphics driver on the computer in question, and that seems to have solved the issue. Good day, all.
