Adding bsmith and mcmanus. ekr mentioned that the RNG might be failing here.

Breakpoint 1, nr_crypto_nss_random_bytes (buf=0x7fff5fbf3c10 "\034", len=4) at nricectx.cpp:90
90	  rv = PK11_GenerateRandom(buf, len);
gdb $ p rv
$1 = 28

Even though it's a worksforme, may still be worthwhile to get a crashtest here.
