More details.

The message comes from plugin/icedteanp/IcedTeaNPPlugin.cc:1506
(of course).  This is from the function plugin_test_appletviewer(),
which is complaining that launching "$appletviewer_executable --version"
failed.  appletviewer_executable is set in NP_Initialize, using the
following logic:

	filename=$(readlink <icedtea plugin soname as obtained by dladdr()>)
	appletviewer_executable=$filename/../../bin/java

Unfortunately, there was a version mismatch here --- my copy of
openjdk-6-jre-headless was from sid.  Downgrading both it and
openjdk-6-jre-lib seems to fix this.

Relevant dependencies:

 icedtea6-plugin/squeeze

	Depends: openjdk-6-jre (= 6b18-1.8.7-2~squeeze1)

 openjdk-6-jre/squeeze

	Depends: openjdk-6-jre-headless (>= 6b18-1.8.7-2~squeeze1)

 openjdk-6-jre-headless/sid

	Conflicts: openjdk-6-jre (<< 6b17~pre3-1)

One fix would be to add a Breaks against openjdk-6-jre (<= squeeze)
to openjdk-6-jre-headless/sid, to deal with upgrades from squeeze.
For the future, I suspect the dependency by -jre on -jre-headless
should be (= ${binary:Version}) to make the changelogs accurate,
anyway[1].

How about this patch (untested)?
