Comparison method violates its general contract!

[luite]

Similar Issue for me - Suggestions or a PM linking to a test build ? :-)

- Installed minimserver on ReadyNas duo v2 as per instructions today
- java 7 on ARM 5 (ejre-7u10-fcs-b18-linux-arm-sflt-headless-28_nov_2013)
- MinimServer-0.63-readynas-arm.bin
- no changes to tag settings (albumsorttag = Album, Artist)
- changed the ohnet.port to 9791
- I do have audiofiles with custom tags

java.lang.IllegalArgumentException: Comparison method violates its general contract!
