vino slowly consumes all available memory

I'm using Linux Mint 17 Qiana with vino package version 3.8.1. When I initially login the vino-server process consumes around 200MB and if close the client, several hours later the memory consumption of the process has blown up to 2.5GB. This will continue until all available memory has been consumed by the process. I expect this to maintain a fairly stable memory profile over the life of the process. I have tried to pinpoint if it's a certain application, but have not been able to. I'm connection from OSX 10.8 via "Chicken of the VNC." If there is any additional diagnostics I can run to help pinpoint the problem further, please let me know.
