Hi, please read the Debian changelog: * Split html documentation in qt4-doc-html package. Now, you have 2 packages: - qt4-doc, it contains documentation in the new help format (sqlite database) - qt4-doc-html, it contains documentation in the html format. Qt assistant use the new help format and Qt assistant_adp use html format. I'll wait for your feedback before closing the bug. cheers, Fathi
