I upgraded to 1.6ZH (kernel plus userland) the other day; since doing so, 
I've had two thread-related aborts from Galeon.  Here's one message:

assertion "target->pt_state != PT_STATE_RUNNING || target->pt_blockgen != target->pt_unblockgen" failed: file "/usr/src/lib/libpthread/pthread_sig.c", line
 790, function "pthread__kill"

Is this a new problem, or newly detected old problem?  I haven't 
recompied Galeon, but I assume that due to dynamic linking that 
shouldn't matter.
