It's not recommended to use `yabar' with `programs.yabar', the (old) stable release
tends to segfault under certain circumstances:
* https://github.com/geommer/yabar/issues/86
* https://github.com/geommer/yabar/issues/68
* https://github.com/geommer/yabar/issues/143
Most of them don't occur on master anymore, until a new release is published, it's recommended
to use `yabar-unstable'.
