\cdot and \times appear the same in equations

[K. Bauer]

OS: Linux Mint 17 Xfce (32bit).

How to reproduce:

    1. Install LyX with `apt-get install lyx`
    2. Insert equation, type `\cdot`

Expected behaviour:
    See a vertically centered dot.

Observed behaviour:
    Saw a verically centered x (the times symbol).
    When exporting to pdf, the correct symbol is shown.

---------------------------------

The issue has been previously (2008) been reported for Ubuntu in general:
    https://bugs.launchpad.net/ubuntu/+source/lyx/+bug/245337?comments=all

The cause was that the required package `latex-xft-fonts` is listed only as "recommended". In recent versions of Ubuntu, such packages should be installed by default.

For Linux Mint 16 the homepage [1] states explicitly, that recommended packages are no longer installed, which presumably reintroduced this bug.

Status changed to 'Confirmed' because the bug affects multiple users.
