Strange dist-upgrade error: libswt2.1-java

[Adam Funk <a24061@yahoo.com>]

When I try to apt-get dist-upgrade, it fails on libswt2.1-gtk2-java 
or libswt2.1-java, but I already have the first one installed and it
it supposed to provide the second, as shown below.  (I'm running 
Debian testing.)  This has been going on for a few weeks now.

How do I fix it?

Thanks,
Adam
