Hi,   probably, it was created by an installer script. By going through the log 
(files) of dpkg, it may be possible to narrow down the list of candidate 
packages using the creation time of /.cache.
Of course, no installation (postinst) script (which are stored in 
/var/log/dpkg/info/) should leave a /.cache directory.

Jörg.
