I too have been bit by this one.  I rebuilt mozilla on a computer running -current
as of May 28 and I get exactly this behavior.  When I start mozilla with my default
configuration that has ~ 12 tabs, mozilla gets a segv.  I've run mozilla in gdb and
found that it dies in different places each time.

Looking deeper into this with GDB, I noticed that there were about 10 running threads
at the time of the crash.  And of those threads, about half appear to have been doing
DNS lookups.

Is there any chance that the new resolver library is responsible for this?  Is it
possible that it's not thread safe?  Or that there's something in the way that
mozilla is calling the new library vs the old one?

>Description:

I build a new kernel and userland, but did not upgrade any pkgsrc stuff.
Now my few days old mozilla binary does not work any more. It can't connect
to any web site, and sometimes does not even start up, showing the profile
manager and asking me to work offline.

>How-To-Repeat:
No idea, it worked with a system ~2 weeks old, I upgraded kernel and userland
to -current as of yesterday. Mozilla (and all other pkgs) have been rebuild
~2 weeks ago too.

The pkg I use is: mozilla-gtk2-1.6nb3
