Comment 2 for bug 996476

Using the source package for 1.3.1 from Quetzal does build but only the first time:

1. wget https://launchpad.net/ubuntu/+archive/primary/+files/viking_1.3-1.diff.gz https://launchpad.net/ubuntu/+archive/primary/+files/viking_1.3-1.dsc https://launchpad.net/ubuntu/+archive/primary/+files/viking_1.3.orig.tar.gz
2. dpkg-source -x viking_1.3-1.dsc
3. cd viking-1.3/
4. dpkg-buildpackage -rfakeroot
5. sudo dpkg -i ../viking_1.3-1_amd64.deb

After this, starting Viking as usual shows version 1.3 in Help->About
It seems to run fine.

However, if I try to build it a second time, it fails:
