Bug#684604: eclipse-rcp: eclipse 3.8 hangs on splash screen with "Loading Workbench" after update from 3.7.2

[Felix Natter]

Package: eclipse-rcp
Version: 3.8.0~rc4-1
Severity: grave
Tags: upstream
Justification: renders package unusable

Dear Maintainer,

I did an apt-get dist-upgrade which upgraded my eclipse from 3.7.2 to
3.8.0~rc4-1.

After the upgrade, when I start eclipse, it hangs at the splash screen with
"Loading Workbench".

After removing ~/.eclipse and restarting "eclipse", I get this log in
~/.eclipse/org.eclipse.platform_3.8_155965261/configuration/1344688663520.log:
