Description of problem:
When installing Lokalize on a fresh Fedora Workstation, and then creating a new project or configuring an existing one, the "Target Language" list is empty. Installing KDE desktop environment solves the problem (Probably a dependency issue).

Version-Release number of selected component (if applicable):
16.12.3

How reproducible:
Every time

Steps to Reproduce:
1. Install Fedora Workstation
2. Install lokalize
3. Open Lokalize and select "Project > Create software translation project ..."
4. Click on the "Target Language" drop down list.

Actual results:
The list is empty

Temporary workaround:
Installing KDE desktop environment seems to solve the problem.

Suggested solution:
Setting the package that includes the list of languages as a dependency for the Lokalize package.
