Everything was being pretty slow on my computer (Kubuntu, using KDE 3.5.1 but issue also occurred in previous versions), when investigating i deduced that Kopete was causing the problem. On a hunch i cleared all the log files (from around Nov 2005, quite large) and everything was fine (after a restart). Judging from the hd activity light on my box there was a lot of disk access going on when the logs were there.
This also happens when editing the bookmarks in Konqueror which i think are also stored in the same sort of format.
Is this an error with Kopete or whatever KDE uses for XML processing? and how do i rectify it, if at all?
Other than that, great program!
