After recent upgrade (testing) Mozilla 1.7.8 will not load pages bcs of PSM

["Randall J. Parr" <RParr@TemporalArts.COM>]

After a recent upgrade of a Debian workstation (built as sarge, now 
tracking testing),
Mozilla 1.7.8 started refusing to load a lot of Java related pages with 
a messages about PSM

mozilla-psm is installed (and has been reinstalled to make sure)

I am using Sun Java 1.4.2_06 JDK / plugin

It was all working just fine before the upgrade. Both Java and Mozilla 
are as before the upgrade.

I can access the same sites just fine using Konqueror (and from RedHat 
system using Mozilla 1.7.6)

Is this a known problem?

Is there a way to fix this?

Thanks
