Crashing on Synology DS1812+ (exception while processing action request)

[catmur]

Hi,
I'me a newbie to MinimServer. I've just installed Java (1.7.0_67) onto my Synology 1812+, and the package "MinimServer-0.8.2-x86.spk".
the install went fine on the Synology, and so did the client (on a Windows 8.1 machine).
When browsing the media server using Windows Media player, I'm getting occasional (i can't pin it to a specific action) crashes, with the following in the logs:

MinimServer[DISKSTATION] is running
MinimServer: exception while processing action request: java.lang.StringIndexOutOfBoundsException: String index out of range: 0

MinimServer error: now stopped, use 'relaunch' or 'exit'

I've no idea where to start debugging this... any thoughts?
