Problem description: I am using the last version of LibreOffice on Linux Mint 16 MATE edition and the graphical environment crashes when I change the colour of the selected text.
Steps to reproduce:
1. Open a new document
2. Select the style to the line (for example head style)(Sorry I am using libreoffice in spanish and I don't know how it is called in english, in spanish it is "formato, encabezado 1" It can be text format or something similar, see the screenshots to localize the menu I mean)
3. Write some words
4. Select those words and change their colour font (in my case, I changed to one of the dark blues)
5. Then the bottom bar of the OS disappears and I have to close libreoffice and change some windows to it appears again.
As you can see in the screenshots, the barof the bottom disappeared in the last screenshot. I Have tried to show you how to reproduce the problem so I hope I can help.
Operating System: Linux (Other)
Version: 188.8.131.52 release
(Tip: If you want to find out how something is called in English, start a program from a terminal setting the environment variable LANG to C. For example: "LANG=C libreoffice-writer".)
