Subject: [BUG] crash while ping-ponging between back-to-back footnotes.
Date: Wed, 29 Jun 2011 17:18:47 +0530	[thread overview]
Message-ID: <81hb78n9i8.fsf@gmail.com> (raw)


Summary: Sample org file down below also doubles up as bug report.

* Sample

  Add footnote-1 using C-c C-x f [fn:1][fn:2]

* Footnotes

[fn:1] This is footnote-1. Jump back to the text by mouse-clicking the
  footnote link. Once you jump back, immediately create another
  footnote reference using C-c C-x f.

[fn:2] This footnote-2. Try jumping back to text by mouse-clicking
  this fn-2 link. Note the following message on the screen "if: Cannot
  find reference of footnote fn:2". Stack trace is attached..
