[O] bug#16265: 24.3.50; re-search-forward (error "Invalid search bound (


From: Keith David Bershatsky
Subject: [O] bug#16265: 24.3.50; re-search-forward (error "Invalid search bound (wrong side of point)")
Date: Sat, 28 Dec 2013 12:44:20 -0800
User-agent: / () / () APEL/10.8 Emacs/24.3.50 (x86_64-apple-darwin10.8.0) MULE/6.0 (HANACHIRUSATO)

Nicolas:

This example demonstrates the problem caused when `org-capture` damages the 
line numbers in the `org-agenda-files`, making it impossible to go to the 
bottom of the buffer with (goto-char (point-max))  --  consequently, 
re-search-backward fails -- other functions fail also, e.g., `org-sort-entries`.
