Bug#883676: Only in Debian build

[Xavier Bestel]

2 things:

- sometimes there are random segfaults, it's reaaally painful when
working with terminals all day long

- I downloaded the binary package from https://github.com/gnunn1/tilix/
releases/download/1.7.1/tilix.zip and ran only the executable (so it
used the debian installed files for everything else), and it doesn't
crash when using the "about" menu item
