IndexError: list index out of range (with solution)

[alvaro@…]

The Problem

Before installing the plugin I could get to my trac (v0.12.5) page on ​http://example.com/trac, but after installing it I couldn't and it throws an IndexError: list index out of range. Funny thing, I could still get to the page using ​http://example.com/trac/ (note the final slash).

The Cause

Taking a look on the traceback I found what was cousing the error: in some files there is a condition checking if the URL matches roadmap or timeline but it asumes that the URL has at least one slash (/) after the base dir. When it isn't (like in ​http://example.com/trac) the index is out of range.

The Solution

In order to fix this you should modify the condition and test first if that index exist (using len(path_elms) > 1). This should be added to the following lines:

• source:simplemultiprojectplugin/trunk/simplemultiproject/roadmap.py#L52​
• source:simplemultiprojectplugin/trunk/simplemultiproject/roadmap.py#L161​
• source:simplemultiprojectplugin/trunk/simplemultiproject/roadmap.py#L248​

• source:simplemultiprojectplugin/trunk/simplemultiproject/timeline.py#L37​
• source:simplemultiprojectplugin/trunk/simplemultiproject/timeline.py#L66​

Hope this helps. Best regards!
