Yes. Its due to the order of the metadata for the files/dirs being
read. 

FMDirectoryView waits on both metadata_for_directory_as_file_pending and
metadata_for_files_in_directory_pending to be read before starting to
read the directory, so if these are both in memory things work out. If
they are not, we get the bug.

Now, for /home that means reading the files ~/.nautilus/metadata called
something like "file:///.xml" (for the directory_as_file) and
"file:///home.xml" (files_in_directory). Since you've
visited /home/user, the metadata file for file:///home is already
loaded, so we're just waiting for metadata_for_directory_as_file. On the
second run both metadata files are cached.

I don't know why it only affected the list view though. Maybe it didn't,
maybe its the fact that we had to load a new view and switch to it
instead of reusing the old view that affected the codepaths taken and
caused the bug.
