I could be missing something here...
Explicit details about a fix should go into the bug tracking system. Users should be able to search for a problem & find out what was done without having to download svn & the source tree.
Agreed.
Use Jira for recording information about the issue raised - for example, a single entry may result in several commits over time, may result in clearer doco, or other changes that are not reflected in the code tree (e.g. wiki updates).
Use SVN for recording information about the specific change being made so that developers reviewing the change can see what was intended or someone looking back at the code (including you 3 years from now) can understand what happened.
Jira and SVN are two of the most critical communication tools for the community - if in doubt, over-communicate.
