GVFS metadata file contains TBB filename/downloaded URLs (Debian Linux)
A forensic analysis of the Tor Browser Bundle on Debian Linux showed that the file ~/.local/share/gvfs-metadata/home contains the filename of the Tor Browser Bundle tarball: tor-browser-gnu-linux-x86_64-2.3.25-5-dev-en-US.tar.gz.
The same file on my personal Debian system does not contain the tarball filename, but does contain names of files I have accessed recently or in the past.
The reports I have read suggest you can delete the contents with no ill effect. Maybe this is something we should consider?
