Error: Macro DiaVisView(net_diagram2.2.dia) failed No such file or directory

[anonymous]

Hi.

First of all, congrats for this great pugin I just installed the plugin, but cannot make it work.

When I try to insert a diagram using this macro:

{{{
[[DiaVisView(net_diagram.dia)]]
}}}

Instead of the diagram image I get a Red-box error saying:

Error: Macro DiaVisView(net_diagram2.2.dia) failed No such file or directory

I also get this log:

OSError: [Errno 2] No such file or directory: 'TRACPATH/attachments/wiki/Name/net_diagram.png'

I have looked in the attachment path, TRACPATH/attachments/wiki/Name/, but only the dia files are present.

Please see the attached dia files, both with and without compression.

I have installed dia-0.97-2 and python-imaging-1.1.6-12.

Thanks!
