Bug still exists in Xubuntu 12.04. Using Thunar will result (sometimes) in not being able to see any of the files in your home directory due to the error in reading the hidden .gvfs folder. The workaround to quickly fix this temporarily (4+ years old bug), is to use:
sudo umount ~/.gvfs
Using this command from a terminal will enable you to browse your home directory again using Thunar.
