rendering of attached embedded images fails with error trace back

Trying to convert a wiki page with Image-macros for attached image files generates the following output in the system log.

If I understand the use of ATTACHMENT_* permissions correctly, they should be translated to specific permissions for the requested realm, however that seems to be missing from the parameters to wiki_to_html?

See also #2240 for the same problem in the EclipseTracPlugin.

This plugin hasn't been ported to 0.11. Patches welcome, maintainers even more welcome.

[asperon]

I have the same problem, and it exists in TracWikiToPdfPlugin

[Filipe Correia]

Has anyone already came up with a patch to this issue?

[Viktor Ferenczi]

See #5856 for a somewhat cumbersome workaround.

[Ryan J Ollos]

Deprecated, please see the TracWikiToPdfPlugin.
