unetbootin application window shows nothing

[Mahmoud]

1) Ubuntu Release: Xubuntu 16.04 LTS

2) Version of package: installed from ppa:gezakovacs/ppa

3) Expected to happen: I expected the application to start up and work.

4) What happened instead: The attached file is a screenshot of what happened. I don't really know how to explain it in technical terms, but nothing loaded. It just stayed like this. At first the spinning wheel icon appeared next to the mouse (indicating that it was loading), but then it just stopped.

The exact procedure of what I did is:
I click on the unetbootin icon in order to start it, it prompts me to enter my password, and and all I get is this blank screen.

I have already tried uninstalling and reinstalling the application and I have installed it from the gezakovacs ppa and the ubuntu repository, but it still just shows nothing.

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

This was fixed a while ago, in release 625, which can be installed from the official upstream PPA ( https://launchpad.net/~gezakovacs/+archive/ubuntu/ppa ).

(the underlying reason is explained at https://github.com/unetbootin/unetbootin/issues/66 - but again, I have already fixed this in the latest upstream release and in the PPA, as of version 625)
