With Inkscape 0.48.5 on a fresh install of Debian 8.2 KDE, if I open the print dialogue and then select "print preview", I get the message:

"Error launching preview. No application is registered as handling this file."

I presume that since KDE is less popular than Gnome for Debian, Inkscape is looking for something that's not installed by default with the KDE desktop. How does Inkscape look for an application for the print-preview?

Is it looking for printing software? Do you have a printer connected to the system?

I do have a printer, an HP Deskjet 3050, and the printing works fine (with the wrong margin size because I have no working preview to check beforehand).

Inkscape itself does nothing special - the application which gets called by the 'Print Preview' command in the GTK2 Print dialog is managed via standard GTK2 settings ( gtk-print-preview-command ), and is not configurable from within Inkscape.

I do not know whether KDE / Qt-based Linux Desktops attempt to override this setting, or ship/install gtksettings with a custom default command (for which you possibly miss some dependencies (?)).

Googling "KDE gtk-print-preview-command" took me to:

https://bugs.launchpad.net/ubuntu/+sour ... bug/243233

... which told me that the bug had previously been found on Kubuntu. It seem that KDE (version 4, at least) does not handle gtk-print-preview-command. The fix was given there in the comments:

Add the line: gtk-print-preview-command="okular %f"
to the file: ~/.kde/share/config/gtkrc-2.0

And that works.

Thanks. problem solved for me.
