The link info to the bugbase is on this Forum's Overview page [ https://forums.adobe.com/community/framemaker/overview ]
The direct link to the bugbase is: https://bugbase.adobe.com/index.cfm
When you log in to the bugbase with your AdobeID, you should see all of the bugs that you have entered, as well as those that you have voted on [i.e. the more people that vote on a bug (or feature), the faster the engineering team will address that particular issue; you can vote on all bugs submitted by anyone, except for yourself]. It's a good idea to browse the bugs and features and cast some votes... 
If you can't find the bug listed, you can use the Search tab to look for the bug. Just remember to select FM from the Product list, specify the type (Bug or Feature or both) and which version (12, in your case), to quickly narrow down the list (there are currently 9 pages of bugs/features listed for FM versions 11 to 2015 of which FM12 has 76 bugs listed). You can also specify your name in the "Reported by" field.
Note: the Execute Search button is in the bottom left corner of the tab window. Do NOT click on the Find Bug/Feature ID button in the upper right corner of the screen.
I did a search and I believe that this is bug that you are referring to: Bug#4093614 - files with referenced graphics are rejected / flushed by Distiller
I think you need to submit more info on what is happening and how you have to do the workaround. If you can, please submit a sample file that always fails for you. IF engineering can reproduce the problem with your file, then the bug will get elevated.
