  a. Install the development scripts: {{{
sudo apt-get install devscripts
}}}

 1. Start the program under control of `gdb`: {{{
gdb <program>
(gdb) handle SIG33 pass nostop noprint
(gdb) run <arguments, if any>
}}}
 1. The program will start. Perform any actions necessary to reproduce the crash
 1. Retrieve a backtrace of the crash: {{{
(gdb) thread apply all bt }}}

 1. If the output gets very long, you might want to use: {{{
(gdb) set logging file backtrace.txt
(gdb) set logging on
}}} beforehand.

 1. Include the complete output from gdb in your bug report		  1. Now you make get a backtrace: DebuggingProgramCrash/Backtrace.

  1. Check if the package has a debugging version available. In general, debugging packages will be named with a -dbg suffix

  2. If not, you can generally* build one this way:

    1. Install the development scripts: 

      sudo apt-get install devscripts

    2. Install the build-time dependencies for the package: 

      sudo apt-get build-dep <package>

    3. Build .debs for debugging: 

      export DEB_BUILD_OPTIONS="nostrip noopt"
sudo apt-get source -b <package>

    4. Install the needed .debs (they will be in the current working directory if the build succeeded): 

      sudo debi <package*.changes>
  3. Now you make get a backtrace: DebuggingProgramCrash/Backtrace.

* most of the packages support the build of debugging version in this way. If that doesn't work for a package you can open a bug against it.
