The purpose of a bug report is to improve the stable and testing Debian Distributions.

You send a bug report to help the maintainer improve the package, not to receive help from him.

The purpose of a bug report

As it is written in :

   The main purpose of bug reports is to help you contribute to the community 
   by improving the next version of the program. Many of the people who report bugs 
   don't realise this-they think that the point is for you to help them individually. 
   Some will ask you to focus on that instead of on making the program better. 
   If you comply with their wishes, you will have been distracted from the job 
   of maintaining the program.

The purpose of bug reports in Debian can be found in the Debian Social Contract :

time limitations

You must keep in mind that maintainers receive a lot of bug reports, and have limited time to spare on Debian. Their priority is to :

  1. package a new upstream release that fixes a lot of bugs
  2. fix a nicely reported bug with a reproducible and a well-identified cause

They don't have time to investigate dubious bug report.
