Thunar 1.6.3; using detailed list view

I have some USB hard drives (that have no defects or bad sectors), formatted
with ext4 and NTFS. The roots of these hard drives contain several hundred
files and directories. I'm not sure whether this problem is caused by the large
number of files/directories, or the fact that I'm using USB hard drives.

When I open a directory in one of the hard drives, and then navigate back
(using the back arrow), about 5% of the time Thunar freezes. Everything becomes
frozen, but menus in the menu bar still work. They can be opened but not
closed, and clicking on the commands in them still works. It seems that every
currently-displayed visual element in Thunar is frozen, but all of the
functionality still works; new visual elements can appear, but they can't
disappear. If I view another program, e.g. mousepad, and then switch back to
the frozen Thunar window, Thunar's window in now covered by Mousepad's GUI; but
still the File menu (and other menus) work, even though the menu bar is gone.
Clicking where the File menu should be brings up the File menu, for example.

Clicking on 'File' -> 'Close Window' closes Thunar like normal, and when Thunar
is subsequently re-opened, it's completely back to normal.
