After Course Restoration HTML entities get broken

Restore and html entities problem

We have several Moodle 1.9.2 installations on different servers and we only have this problem in one using PHP 5.2.6 on Fedora Core 9

If we try to recover a backup the html entities in the embedded text gets broken.

The backup system appear to work well. We can restore any backup on a different machine without problems.

Obviously the problem is related to something in the system, maybe PHP but I can not see the difference. In the servers that works I use a similar setup but with CentOS5.

All Moodle installations at the same server have this problem.

Look at the screenshots. I think they explain the problem very well.

Thank you.
