Firefox won't start (again!)

[cpghost]

On a RELENG_5 system from June 30th (source and ports),
firefox-1.0.4 won't start. It just hangs in the kserel state.
This is on a diskless system using NFS.

Running truss(1) on the hanging firefox-bin process shows:

kse_release(0x8065fa4) = 383 (0x17f)
kse_release(0x8065fa4) = 0 (0x0)
kse_release(0x8065fa4) = 383 (0x17f)
kse_release(0x8065fa4) = 383 (0x17f)
kse_release(0x8065fa4) = 0 (0x0)
kse_release(0x8065fa4) = 383 (0x17f)
kse_release(0x8065fa4) = 383 (0x17f)
kse_release(0x8065fa4) = 0 (0x0)
...

When starting, firefox generates a GNOME Warning:

Gdk-WARNING **: gdk_property_get(): length value has wrapped in
calculation (did you pass G_MAXLONG?)

But thunderbird does the same, though it doesn't hang.

/etc/libmap.conf is empty.

Any idea?

Thanks,
-cpghost.
