#5600: pthread_self() sometimes returns NULL

Following issue is very odd. I have a gcc4 binary called metacity which
uses glib with pthreads. Sometimes pthread_self() returns NULL and
metacity crashes.
When I run metacity with LD_PRELOAD=any_existing_library_or_binary then it
works.
Debug code in glib (gthread) library:
{{{
fprintf(stderr, "pthread_self(): %p\n", pthread_self());
}}}
{{{
~> metacity
pthread_self(): (nil)
Kill Thread
~> LD_PRELOAD=/bin/ls metacity
pthread_self(): 0x323ee0
Window manager error: Unable to open X display
~> LD_PRELOAD=libroot.so metacity
pthread_self(): 0x2fdee0
Window manager error: Unable to open X display
}}}
