Description

Hi..

I've installed Graphviz, i got this error if i print it as pdf (using TracWikiPrint-Plugin), if i don't insert graphviz code in the wiki site, the pdf just doing fine and don't get this error. Can these 2 Plugins work together? or did i miss something in the installation? Could somebody help me? Thank you in advance.


Oops…
Trac detected an internal error:

AttributeError: 'NoneType' object has no attribute 'bands'

This is probably a local installation issue.
Found a bug in Trac?

If you think this should work and you can reproduce the problem, you should consider creating a bug report.

Note that the TracWikiPrintPlugin plugin seems to be involved. Please report this issue to the plugin maintainer.

Before you do that, though, please first try searching for similar issues, as it is quite likely that this problem has been reported before. For questions about installation and configuration of Trac or its plugins, please try the mailing list instead of creating a ticket.

Otherwise, please a new bug report describing the problem and explain how to reproduce it.

I think you hit the PIL bug described in #6767, related with using 32 bit images. Can you confirm if the proposed fixes work?

Thanks.
