 * Set some usertags to allow for clever indexing of debreaper reports.
 * Add intelligence in debreaper to search those reports.
 * Detect whether the trace was generated with enough debugging 
   symbols.
 * Allow the user to download and install more debugging symbols (not 
   easy without the ddeb's).
 * Support Qt (probably not possible with dlopen, or will need a C 
   wrapper library).
