Not sure if I should have reported this again sooner than this.
As I reported on April 18th org-collector works as expected using GNU Emacs 24.4.1 (i586-pc-linux-gnu, GTK+ Version 3.14.5) of 2015-03-07 on binet, modified by Debian Org: 8.2.10 release_8.2.10 but fails if GNU Emacs 24.4.1 (i586-pc-linux-gnu, GTK+ Version 3.14.5) of 2015-03-07 on binet, modified by Debian Org: 8.3beta release_8.3beta-1030-g65bbb1 now version Org-mode version 8.3beta release_8.3beta-1191-g9e1591
