firefox hangs on 6.2-PRERELEASE amd64

Fri Nov 3 16:26:24 UTC 2006

Yesterday I updated my amd64 STABLE box to 6.2-PRERELEASE.

After the upgrade, firefox started to hang. I can reliably trigger this
my clicking on the [Manage...] button in the "Content" tab of the
preferences dialog. The same happens when trying to access some websites.

Both firefox 1.5.0.7 and 2.0 hang, which suggests something external.

I'm running a custum kernel. The only thing I added with the upgrade was:
options         HWPMC_HOOKS
device hwpmc

Running a ktrace on firefox didn't give very much;

After starting firefox, I see a defunct process, that's probably a child
of firefox:

16772  v0  I      0:00.00 /bin/sh /usr/local/bin/firefox
16776  v0  I      0:00.00 /bin/sh /usr/local/lib/firefox/run-mozilla.sh /usr/lo
16780  v0  S      0:01.87 /usr/local/lib/firefox/firefox-bin
16785  v0  Z      0:00.01 <defunct>

I tried attaching gdb to a running firefox-bin, but that produced an
internal error in gdb which made it dump core. :-(

Also, when starting firefox from an xterm, it produces a warning:

GConf Error: Failed to launch configuration server: Failed to execute child process "/usr/X11R6/libexec/gconfd-2" (Invalid argument)

GConf Error: Failed to launch configuration server: Failed to execute child process "/usr/X11R6/libexec/gconfd-2" (Invalid argument)

But I'm not sure if this is related.

During system startup I get the following message:

Nov  3 07:09:26 slackbox root: /etc/rc: WARNING: $compat5x_enable is not set pro
perly - see rc.conf(5).

But I'm not sure this is related either.

Help please? :-(
