There doesn't seem to be anywhere to report a bug, so hopefully VMWare staff read these forums...
After "upgrading" to version 9.0.3, a serious bug emerged. Host is Ubuntu 12.10.
Inside a guest running Ubuntu Linux, when I start FileZilla, the guest completely hangs for several minutes. Eventually FileZilla starts. However, if I do it a second time, the guest crashes after a several minute wait. In this case, WS thinks the guest is still running though it clearly is not. vmrun won't reset or stop the guest (it hangs for several minutes before saying so). Only way out is to reboot the host.
This problem does not occur on version 9.0.2. I've uninstalled 9.0.3 and reinstalled 9.0.2 to confirm.
I posted the link in case you had an active support agreement and you wanted to choose that route. If not, then posting in the appropriate product community on the VMware Technology Network is the other option!
