[Samuel Kreuzer]

New installation of "kicad (4.0.7+dfsg1-1ubuntu2) bionic" on Ubuntu 18.04, wxWidgets 3.0.4.
On opening GerbView, the program displays the dialog with the following content:
"An assertion failed!"
"../include/wx/math.h(151): assert "x > INT_MIN - 0.5 && x < INT_MAX + 0.5" failed in wxRound(): argument out of supported range"

Backlog:
ASSERT INFO:
../include/wx/math.h(151): assert "x > INT_MIN - 0.5 && x < INT_MAX + 0.5" failed in wxRound(): argument out of supported range
