I've got a very strange behaviour of my image...

It's all ok with Image Persistency on locally on my windows PC. But when I switch to it at hosting (it's webfactional.com with ubuntu) our site stops to answer (after saving the image, if I understand correctly). When I click on "snapshot" in "System Management" I get the following walkback in browser:

Internal Error

Without any buttons, nor anything visible in Pharo (using VNC). But "Process Browser" shows no process for Seaside... How can I find the cause of the problem and/or fix it?
