All plugins stop work when GRECLIPSE is installed on Eclipse

[Anselmo Junior]

Steps to reproduce the issue:
1 - Get a clean eclipse install by APT (apt-get install eclipse)
2 - Help->Install New Software
3 - Using this update site http://dist.springsource.org/release/GRECLIPSE/e3.7/, install "Groovy-Eclipse (Required)". Restart Eclipse.
4 - In Help -> About Eclipse Platform, the groovy icon does not appear, but can be see in "Installation Details". I don't any plugin stuff like create a groovy project, create groovy class, etc.

If I try to install other plugins, and then install the groovy-eclipse, all other plugins stop to work, including the groovy-eclipse.

First I open this issue on Jira Codehaus, but in discussion we conclude that the problem is on how the eclipse is packaged.

As project lead of groovy-eclipse, I am willing to help find out what is going on here. It is likely something to do with permissioning, but I am not certain.

Status changed to 'Confirmed' because the bug affects multiple users.

I've installed the 3.7 groovy plugin but after eclipse restarts most windows are not present (other plugins not seen). The install completed with no errors. This is on Ubuntu Precise Pangolin 64bit.

Removing the install restores normal behaviour.
