For some reason Banshee is flaky at the moment. So, I tried the Firefly Java client. No luck there either.
I then tried the later version, svn-1696, but for some reason it keeps giving me an error message when I try to start it, namely that the plugin dir is not defined. Of course it is; the exact lines from the latest config with the source.
If you have any more suggestions, let me know.
For the time being, I have reverted to v0.2.4.2.
