#1421: GetComponents shows uninitialized variable due to typo
---------------------------+------------------------------------------------
 Reporter:  knarf          |       Owner:  eric9     
     Type:  defect         |      Status:  new       
 Priority:  major          |   Milestone:  ET_2013_11
Component:  GetComponents  |     Version:  ET_2013_05
 Keywords:  ET_2013_05     |  
---------------------------+------------------------------------------------
 When trying to update from an existing checkout I got:
 {{{
 Use of uninitialized value $, in concatenation (.) or string at
 /home/knarf/bin/GetComponents line 1632, <STDIN> line 1.
 }}}
 This is caused by a typo (an additional "$") in the script. However, I
 found that one of the arguments in the relevant comparison also needs a
 'chomp' to compre successfully, which I also added in the attached patch
 that I propose to also apply to the last release.
