Guitarix has been updated to 0.41.0 by commit
bf592ef506e1db0340dc11faa0514fe80793e6d6.

I have tried "guix build guitarix --no-grafts --check -K" at least 10
times without noticing an unreproducible behaviour.

Could someone confirm this and then close this almost 5 years old bug?

I propose to open another bug report to track the waf-based packages issues.


All the best,
