[Debian-astro-maintainers] Bug#858094: no spectrum is displayed

[Thibaut Paumard]

Control: tags -1 fixed-upstream

Hi,

The bug has been identified by upstream as something that they have
fixed in their internal development version. It has to do with the
numeric separator in some locales. Unsetting the locale works around the
problem:

$ LANG= QFisView

Kind regards, Thibaut.
