metadata.xml for kmymoney has upstream pointing to "<remote-id type="sourceforge">kmymoney2</remote-id>" but KMyMoney has not actively used SourceForge for many years, and has also been kmymoney4 instead of kmymoney2 for that time. (I don't know if it will switch to kmymoney5 for the frameworks branch, but that is still a bit in the future.) It is now fully a KDE project. (the metadata info is the same for the kmymoney-9999 build in the kde overlay, but I don't know if this bug can have both corrected. Looking at metadata.dtd, I don't see an appropriate value for remote-id. Would it make any sense to add one specifically for kde? I suppose bugs-to or doc could be added for kmymoney.
Tarballs still released there: https://sourceforge.net/projects/kmymoney2/files/KMyMoney-KDE4/ remote-id is used for example by euscan to check if new releases available, so it is not incorrect.
