Can confirm this happens on LTSP thin clients from NTA. AIGLX -> off, and Composite -> disable avoids the assertion failure. This is latest Karmic with corresponding LTSP /opt/ltsp/i386 tree. FYI on a thin client it simply freezes the client, requiring a power cycle. I was lucky enough to be able to add an RS-232 terminal w. getty to be able to see the X server's assertion failure.
