Version: 0.80.2 (using KDE 4.3.2) OS: Linux Installed from: Ubuntu Packages Kopete shouldn't use it's own XML format for chat logs. As far as I know, there isn't a viewer for them. Kopete should use 100% standard HTML for chat logs, as that is viewable in a web browser.
Kopete has its own viewer for XML history. And now there is new version of history plugin which using SQLite. Because of this I will mark this bug as WONTFIX.
