Knime 1.3.5 unstable in Linux ?

Hi Guys.

Sorry for my late response,
I was very busy with learning and coding for university and work.

I've tried to create a KNIME from an unmodified Eclipse like you've said.

KNIME installed well using the UpdateManager.
I've also installed GEF.

But if I open a new KNIME workflow it shows me an "Error Page":

Error opening the editor.
An error occurred while automatically activating bundle org.knime.workbench.editor (158).

What should I do? :)

Greetings,
imax.
