12.04 systray crashes randomly

since a few updates ago my systray crashes randomly, hence unable to access any apps that have been whitelisted. Only way to get it back without restarting is to run unity --replace. but this causes other graphical issues with apps that are open. Like being unable to click on apps in the launcher, some apps not have borders, can't bring apps to foreground etc etc. Not an ideal workaround.

Please let me know what info is required to troubleshoot, I am not sure where to get info for the systray.

Thanks
