Markdown links not resolved properly

I'm trying to create a link to the bitbucket file viewer, but the links are not pointing to the proper place when using the [link display text](url) markdown syntax. For example, both the following links should point to the same place, but the markdown one points to this page.

https://bitbucket.org/osrf/gazebo/src/8f2b990230cd32df220034bbb98aa6c9f47af8c2/gazebo/physics/World.cc?fileviewer=file-view-default#World.cc-2180:2198

the same link points elsewhere

paste of raw code of this issue:

[the same link points elsewhere](https://bitbucket.org/osrf/gazebo/src/8f2b990230cd32df220034bbb98aa6c9f47af8c2/gazebo/physics/World.cc?fileviewer=file-view-default#World.cc-2180:2198)

EDIT: further debugging shows that it is the : character separating the line ranges 2180:2198 is the culprit. Removing the : allows the Markdown to parse correctly, though the link is broken.
