Bug#1057033: nemo: Several MIME types not recognized on GVFS mounted volumes

[Andreas Heinlein <aheinlein@gmx.com>]

Package: nemo
Version: 4.8.6-2
Severity: normal
X-Debbugs-Cc: aheinlein@gmx.com

Nemo fails to recognize several MIME types, namely *.pgp 
(application/pgp-encrypted) and *.doc (application/msword) when the files
reside on a network drive mounted with GVFS (SMB share on NAS). Instead it
shows "application/octet-stream" and doesn't know how to open it when
double-clicking it. When copying the files over to a local drive,
the MIME type is recognized correctly. Other files types, e.g. PDF or ODT,
work as expected.

Problem also occurs in Debian bookworm, but does not occur in latest Linux
Mint with Nemo 5.8.4. Problem does *not* occur with nautilus, so I guess it
is not a GNOME thing.
