[Pharo-project] Downloading configuration on Pharo1.3 and Pharo1.4 freezes my image

Hi! Some students had their Pharo1.3 and Pharo1.4 images freezed when executing the following script: Gofer it squeaksource: 'ObjectBrowser'; package: 'ConfigurationOfObjectBrowser'; load. (ConfigurationOfObjectBrowser project version: #bleedingEdge) load I've reproduced it with the last images from Hudson/Jenkins, and they allways freeze on the Cleaning up step... On the other hand, it loads correctly on latest 1.2... Does anybody have an idea of what's happening? Thanks, Guille
