Kepler keeps hanging when creating new Activiti Diagram

I'm using ArchLinux and the latest version of Eclipse kepler and Activiti Designer. But when I create a new Activiti Diagram in Eclipse, the program keeps hanging. The progress bar on the bottom right shows 'Remote System Explorer Operation' initially. After I googled about this problem and modified

Do you have xml validation on? Might be worth a try to disable it (http://www.jorambarrez.be/blog/2013/02/19/uploading-a-funny-xml-can-bring-down-your-server/ - eclipse has the same issue)

I have the same problem (not only with Kepler, but with previous Eclipse versions too.)
I've tried disabling XML Validation, but this doesn't solve the problem for me.

After I kill Eclipse and reopen in - the process diagram appears to be there, but I can't do anything with it. Respective eclipse window seems to be frozen anyway.

This error window also pops up: http://i.imgur.com/b77MXIQ.png

last strings in eclipse .log file:

<code>!ENTRY org.eclipse.ui 2 0 2014-05-28 19:21:58.272

Yes, I'm experiencing the same problem with you, every version of Eclipse will suffer from this issue. And it seems has nothing to do with malicious XML files, as I'm just creating new Activiti Diagrams, not importing an existing one.
And Eclipse will freeze after opening a .bpmn file too!
What's your OS type? Was it a Linux too? I'll try to run Activiti on Mac OS X later on. If it works well on Mac, I'll report it.

I have already tested Activiti Designer on Windows7-64bit + Eclipse kepler. The whole things work very well. No fault at all.
This is annoying, I'd prefer Linux as the development environment.
Had anybody using Arch or other distributions of Linux succeded on running Activiti Designer, please let me know!

Mac+Kepler works well too, I'll try again on other distribution of Linux another day

Thanks, bidek! Installing cups and starting cupsd helps!

As mentioned by @bidek - cups is needed for this to work.

To be precise. CUPS is not needed, when we disable printing support in eclispe. See linked topic
