Closing the application during the export of my project. Recorded video is therefore not complete

[Romane PETIT]

Hello, I'm sorry, I'm french so not talk very good english.

Operating System & version: Linux Mint 17,3 Cinnamon 32-bit, Ubuntu 4.8.4
Version Cinnamon : 2.8.8

Version of Openchot installed : with the PPA :

         UseStable PPA (Contains only official releases):
             sudo add-apt-repository ppa:openshot.developers/ppa
             sudo apt-get update
             sudo apt-get install openshot-qt

It's Open shot version 2.4.3-dev1

I made a video of 2min with titles, photos, videos (gopro), music. When I export in to my computer, to 80% of the export, the crash software and my video does not register in full.
I tried all possible video formats, it's the same thing every time.

Thank you
Cordially,
Romane
