On Wednesday, Burkhard Lück began sending mails to the kdegames mailing list about the shortcomings we had regarding translations not being loaded, not being possible, etc.
One of the most reported issues was that translations of theme names were not used even though they had been translated. That shocked us as we use the typical KDE way of using .desktop files, so we investigated a bit, and came up with with a very small test case that showed that the kdelibs class for accessing .desktop files was not working correctly.
In less than two hours we had the bug fixed. So that's why small KDE projects like kdegames are useful for KDE, they are as good testers as anyone else.
