DQC Crashes on Ubuntu

Reported for version 9

Problem

DQC crashes on Ubuntu 14.04 LTS. The issue repeats less or more often. 

Solution

DQC desktop GUI is an Eclipse-based application. The error is a common error of Eclipse (Kepler release, v4.3) on Ubuntu. There are two possible workarounds:

In the file [DQC]/configuration/config.ini add the line org.eclipse.swt.browser.DefaultType=mozilla.

If the error still remains, another possibility is uninstalling the package /usr/lib/x86_64-linux-gnu/libwebkitgtk-1.0.so. After this step, Eclipse will be forced to use the package libwebkitgtk-3 and the crash will not happen.

As of newer platforms (Eclipse release Luna v4.4 and higher), the bug had been fixed, therefore upgrading Eclipse or downloading a new package solves the issue as well.
