Titanium closes with fatal error after few seconds startup

I just installed Titanium (VERSION 3.4.1.201410281727) in Ubuntu 14.04 (64 bit) following the Installation and Configuration guide, I've double checked fulfilling the prerequisites and the software location, but every time I start Titanium it closes after few seconds with the following message:

./TitaniumStudio
