Bug 1147619

Description of problem:

Doing a search in evince increases its memory footprint significantly.  Performing another search does not release the memory for the previous search, so evince just keeps growing and growing until closed.

Version-Release number of selected component (if applicable):

evince-3.10.3-1.fc20.x86_64

How reproducible:

Always

Steps to Reproduce:
1. Open some large PDF (I noticed this looking at the C++ standard)
2. ps u | grep evince
3. In evince, search for a word that occurs frequently
4. ps u | grep evince
5. Notice that evince is using much more memory
6. In evince, search for a word that never occcurs
7. ps u | grep evince
8. Notice that evince is using slightly more memory
9. In evince, search for the first word again
10. ps u | grep evince

Actual results:

The evince process grows with each search.

Expected results:

The process should not grow after the first search, since the subsequent searches are no larger.
