Running Skype 2.2 on Linux Mint 16

It works for 32bit and 64bit Mint 16 (I tested on Mate)
I use skype-ubuntu_2.2.0.35-1_i386.deb

if you try to start skype from teraminal, this is what you will see

$ skype
Segmentation fault

To fix this, download

libglib2.0-0_2.34.1-1ubuntu1_i386.deb

 from

http://packages.ubuntu.com/search?keywords=libglib2.0-0

quantal-updates (libs): GLib library of C routines
2.34.1-1ubuntu1: i386

extract deb file (you can do it whit the graphical archive extractor)

 and then start skype with prealoded lib like this:

$ Exec=env LD_PRELOAD=/home/{user}/Downloads/libglib2.0-0_2.34.1-1ubuntu1_i386/usr/lib/i386-linux-gnu/libgobject-2.0.so.0.3400.1 /usr/bin/skype

Test your skype, type in:

You should not see text! :) Like me! :)

Mint 16 currently use "2.38.1" version of GLib C routines.
I tried preload newer version  "2.39.4", with the hope that they fix it,
 bus sadly they don't and the outcome was the same.
