Description Enrique Artal 2014-05-28 14:26:24 UTC 
If I put LaTeX formulas in an annotation for a pdf file (inside double dolars), the system offers to me rendering it. I check that the image is created in /tmp but not displayed and I cannot edit the source (except with undo)

Reproducible: Always

Steps to Reproduce:
1. Write a Latex formula in an annotation
2. Click to render it
3.
Actual Results:  
No result, no error

Expected Results:  
The Latex output with the text

It is running in an update Fedora 20 computer

Can you please tell a latex formula you're using for this?

$$E=mc^2$$
Comment 3 Enrique Artal 2014-06-18 06:55:36 UTC 
Any test formula, say $$a^2=1$$; the png file exists in /tmp but nothing appears in the note
Comment 4 Albert Astals Cid 2014-06-18 23:08:24 UTC 
Right
Comment 5 Enrique Artal 2014-09-25 10:27:40 UTC 
I am now in okular 0.20.0 and still no rendered image; has anyone the same problem? I still do not know if it is a conf problem. Thanks, Enrique.

Well, the bug is marked as confirmed, no?
Comment 8 Enrique Artal 2014-09-26 11:59:09 UTC 
Right, I skipped the status. One colleague who is still at Fedora 18 had no problem (okular 0.16.5), I do not know if this is helpful.

Fix latex render in annotations

We need
  disconnect(textEdit, SIGNAL(cursorPositionChanged()), this,SLOT(slotsaveWindowText()));
and it's counterpart, otherwise when inserting the image, the cursor pos changes, slotsaveWindowText is called, the content is passed by a toPlainText and set again and kaboom the content is lost

Also a few extra const
