Comment 1 Matthias Bentrup 2012-06-20 09:16:05 UTC 
I think you have to check the GL_VERSION >= 3.0 first, to make sure that glGetStringi is actually supported. The GLX spec states explicitly:

"A non-NULL return value for glXGetProcAddress does not guarantee
that an extension function is actually supported at runtime. The
client must must also query glGetString(GL_EXTENSIONS) or
glXQueryExtensionsString to determine if an extension is supported
by a particular context."

We ended up fixing this in Bug #1620.
