Also I managed to install mutter debug symbols now, a better stack trace
showing that the error may come from free_glx_pixmap:

/* FIXME - we need to trap errors and synchronize here because
* of ordering issues between the XPixmap destruction and the
* GLXPixmap destruction.
*
* If the X pixmap is destroyed, the GLX pixmap is destroyed as
* well immediately, and thus, when Cogl calls glXDestroyPixmap()
* it'll cause a BadDrawable error.
*
* this is technically a bug in the X server, which should not
* destroy either pixmaps until the call to glXDestroyPixmap(); so
* at some point we should revisit this code and remove the
* trap+sync after verifying that the destruction is indeed safe.
*
* for reference, see:
* http://bugzilla.clutter-project.org/show_bug.cgi?id=2324
