So that this doesn't get forgotten: Some of the scripts can cause focus problems, e.g. using xdg-email in KDE while KMail is already running results in the composer window open in the background. See http://lists.freedesktop.org/archives/portland/2006-August/000768.html for more details and possible ways of fixing.
Lubos Lunak Do you still experience this issue with newer soft ? Please check the status of your issue.
I expect this problem hasn't just magically gone away, but if nobody else cared for so many years, I guess it doesn't matter.
