I resolved this issue (on my system) by reinstalling libequinox

$ sudo apt-get install --reinstall libequinox-osgi-java

The debug output claimed that the framework has been found, but this was 
a lie since:
/usr/lib/eclipse/plugins/org.eclipse.osgi_3.8.1.dist.jar was missing.

Maybe there needs to be better sanity checking here.....
