Yesterday I checked in a few changes to xmesaP.h, xmesa1.c and xmesa2.c
which fixed some problems with 24bpp rendering and buffer clearing.

Can you get a more detailed stack trace?  Setting the MESA_XSYNC env var
first will force Xlib to operate synchronously and should make it easier
to locate the problem.
