Problems with template deletion

If I remove a template from template.xml (but do not remove the template JSPs), the template and its details is still present in the jahia_pages_def table. Nevertheless when I navigate to a page based on that template, I get an exception and cannot display it.

Furthermore even if I have already deleted all pages , based on that template, prior to removing it from template.xml, I get the exception:

01.10.2008 14:27:16 ERROR [main] PageDefinitionHelper: Unable to find template 'MultilingualSearch' in the template set for site 'testSite'. There were already 1 page(s) created with this template. IDs: [40]. This will cause an exception when one of these pages will be called. (PageDefinitionHelper.java, line 152)

When going to Administration Center -> Manage templates manual deletion is not working as I get:

2008-10-01 14:36:07,328: ERROR [org.jahia.bin.JahiaAdministration] - Error during templates operation of a new element we must flush all cac
