Description free.nomadic.life 2011-09-21 14:56:24 UTC 
Created attachment 197164 [details]
opened system monitor showing that the evince is using 100% processor and enourmous amount of memory, when a text is selected.

THe evince text selecting feature works so far with most of the opened pdf documents. But there are some documents, which after a text is selected in evince make it freeze. The same documents can be opened and scrolled as long as a text selecting tool is not used.

How to reproduce the bug:
Here are some links of pdfs with which I have observed it:

http://gsd.uwaterloo.ca/sites/default/files/clafer.pdf
or 
https://github.com/gsdlab/clafer/raw/master/doc/tutorial/doc.pdf

1. Open one of the above pdf documents and try to select text

Note: If the selected text is a word or a line , the application freezes for a while and then continues to work
If a paragraph or more is selected it totaly freezes and even slows down the whole machine.
