The interface is nice, but I couldn't use it properly. When I removed my SDHC card it started correctly and listed the few preinstalled MP3s (those in ~/.sounds). But when I inserted my SDHC with 8 GB of MP3s and Oggs and FLACs, it crashed while scanning the tags. The same happens with earlier releases of UKMP, too. I suspect the tag scanner isn't very robust. Is there a good way to find out at which file the crash occurs?
