Delete vias will make a 'Segmentation fault (core dumped)' kicad nightly on Linux

[easyw]

Hi @jsreynaud
I've discovered that the recent KiCAD nightly on Linux has introduced an issue when deleting the vias through the plugin...
This issue is not present on Windows.

I've done a repo to test this issue, limiting the code to the deleting part...
https://github.com/easyw/DeleteViasTest
inside there is also a test board
With the DeleteViasTest plugin I cannot get the core dump, but not all the vias are deleted after calling the function... this is weird and doesn't happen on Windows builds.
