*** vivid SRU justification : fldigi (3.22.04-1ubuntu1) ***

[Impact]

 * Access of some uninitialized structures at startup manifests either
   as a no-op or a crash, depending on the state of the user's fldigi
   application configuration file(s).

 * This affects a substantial number of fldigi users upon upgrade to vivid,
   as noted by this bug, its duplicate, and many posts on the linuxham mailing
   list (noted in the patch).

 * The vivid SRU upload (3.22.04-1ubuntu1) applies ONLY the one-line patch
   (attached to this bug) which prevents access of the structures until after
   they've been initialized.  That patch has been applied to Debian unstable
   and Ubuntu wily (as of 3.22.08-2), and has been submitted upstream.

[Test Case]

 * Testing the fix required an fldigi configuration state which happens
   to trigger the crash.  This fix has been successfully tested by two
   users who did experience the crash.  This procedure may or may not
   result in a crashing configuration.

   1. Start up an older version of fldigi and configure it via its setup
      wizard.
   2. Upgrade fldigi to version 3.22.04-1 and try starting it.
   3. Observe crash with dump referring to "fl_height" (see bug report).
   4. Upgrade fldigi to version 3.22.04-1ubuntu1 and try starting it.
   5. Observe no crash.

[Regression Potential]

 * Regressions resulting from this fix seem unlikely.  The changed
   routine relates to font and window sizes.
