Re: 5.1.0-rc1


Hi, I'm failing to find this issue in the bug tracker, so please let me
know if its already reported. If not I can report it.

Every time I launch pcbnew with a plugin in /home/marcos/.kicad_plugins/ it
immediately crashes. It starts normally if I remove .kicad_plugins. This is
the plugin that makes it crash:
