_mesa_reference_renderbuffer: Assertion `oldRb->Magic == 0xaabbccdd' failed

Description
Latest Ubuntu Karmic, KDM login for an NTA thin client under LTSP. When trying to start a KDE session the thin client's X server dies with:
X: main/renderbuffer.c:2159: _mesa_reference_renderbuffer: Assertion `oldRb->Magic == 0xaabbccdd' failed
There is plenty of memory, and Ratpoison and WindowMaker logins do not encounter this failure. There was no sign of this assertion failure in any logs; I had to run X manually from a RS-232 session connected to the thin client to see this failure message.
