Description Alberto Garcia 2014-03-20 14:48:11 UTC 
This happens with 0.7.11, but not 100% of the times. A way to
reproduce seems to be to select several regions of text.

Here are the steps:

- Load one or more pictures
- Recognize text
- Export as PDF (searchable PDF)

Traceback (most recent call last):

Thanks for reporting. It was happening when attempting to export to PDF a document having a text area with no text. It will be fixed in the next version.
