 I'm getting some strange errors when running the updater on a very hacked-
 up version of Tor Browser on Linux. In one instance, I got
 "ensure_copy_recursive: path is not a directory: /home/user/tor-
 browser_en-US/Browser/TorBrowser/Data/Browser/profile.default/Cache/4/99,
 rv: 0, err: 24". In another (when I enabled app.update.logs) I got:

 {{{

 }}}

 Oddly, while trying to reproduce this more times, the update finally
 downloaded successfully and applied fine. This caused me to suspect a bad
 mirror, but that full MAR file seems fine on all mirrors.

 I am out of ideas, and I have not been able to reproduce this issue on any
 vanilla TBB on the same systems, even if I force it to do a full update by
 editing the start-tor-browser script.
