no PDF previews on remote ssh shares?

["Sascha Heid" <saschaheid gmail com>]

Hi List,

i have many thousand ebooks shared and access them with nautilus'
builtin "connect to ssh server" thingie from my Laptops.
Works great but i get no pdf previews even though i have the settings
in nautilus on "always" and "1GB".
It tries to make pdf-previews when it loads new folders but ends up
displaying the icon instead.
I get previews of pictures though.

Im running gnome-2.22 on all computers.
Updating to the latest poppler/evince/nautilus on one of the clients
did not change anything.

Are pdf previews on remote shares working for anybody?

Regards
Sascha
