Hi,
No problems down the line.
The proxy error.. is more of a notification that it didn't find a configuration file for configuring a proxy connection.
That is no problem, unless you are using a proxy to connect to the internet.
Most people don't use proxy connections..
The other 2 errors.. they are from the toolkit to draw things on screen. I've always seen some gtk errors/warnings for as long as I've used VMware Workstation/Player on Linux and have learned to ignore those.
