ssh X11 forwarding gives X error when launching an OpenGL application

I'm connecting to a server running SLC 6.7 with ssh with X11 Forwarding enabled.

When I try to execute 'xclock', the program launches and exectues just fine.

When I try to execute 'glxgears', I get the following X11 error:

LIBGL_DEBUG=verbose glxgears
libGL: screen 0 does not appear to be DRI2 capable
libGL: OpenDriver: trying /usr/lib64/dri/tls/swrast_dri.so
libGL: OpenDriver: trying /usr/lib64/dri/swrast_dri.so
libGL: Can't open configuration file /afs/cern.ch/user/m/mkrafczy/lxplus/.drirc: No such file or directory.
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  154 (GLX)
  Minor opcode of failed request:  3 (X_GLXCreateContext)
  Value in failed request:  0x0
  Serial number of failed request:  33
  Current serial number in output stream:  35

Does anybody know what the problem might be? I've recently come from ubuntu, and this issue didn't occur then. Also if I use another machine, such as one with CentOS 6, the issue also doesn't occur.
