found 1000230 1.0-2 severity 1000230 normal -- Got it. Thanks anyway, Georges! Peter 24.02.2022, 16:56, Georges Khaznadar < mailto:georges.khazna...@orange.fr georges.khazna...@orange.fr > Thank you for the bug report, Peter. However, I shall not try to fix it shortly. I suspect that those errors are due to some wrong interaction between Ruby and Gnome libraries at some point, but I did not find enough information about those "critical" errors when I tried to fix them in the past. Those errors did not entail misbehaviors of the application so far (as I could check individually), and most users will not even notice them when they launch screenruler from a graphic menu. Best regards, Georges. Peter Mueller a écrit : > reopen 1000230 > found 1000230 1.0-2 > thanks > -- > 1.0-2 works now. Thanks a lot!!! However, some error messages emerge. > 1.
