I built Firefox, Thunderbird and Dillo from pkgsrc and each of them
crashes with the same error:

root@netbsd:~ # firefox
assertion "qhead->pt_spinlocks == 0" failed: file
"/usr/src/lib/libpthread/pthread_run.c", line 266, function
"pthread__sched_bulk"

root@netbsd:~ # thunderbird
assertion "qhead->pt_spinlocks == 0" failed: file
"/usr/src/lib/libpthread/pthread_run.c", line 266, function
"pthread__sched_bulk"

Same thing happenes with Dillo. It runs for a few seconds but when it
has to render a page crashes. As you can see - neither Firefox nor
Thunderbird even runs.
I got the same error on a clean NetBSD 2.0.2_STABLE install and on
2.0.2_STABLE built by me.
Any suggestions? I've no clue...
