Notes

Issue is cosmetic only.
The "confluence-icon-multimedia.svg" file is not included in the confluence-icons-1.0.3.jar file.
See https://bitbucket.org/atlassian/confluence-icons/overview for list of svg files that should be included within the jar.

Workaround

As it is cosmetic no workaround is needed however copying one of the exiting .svg files, renaming it to "confluence-icon-multimedia.svg" and repackaging the jar will prevent the stacks, however the wrong icon is displayed.
