Labcenter Ares Gerber file parse error

Hello,

I've been trying to load a gerber file generated by Labcenter Ares. The file parsing crash with the following python traceback:

[DEBUG] Line 4379: Aperture change to (10)

I've attached the input gerber file for reproducing the issue.

Gerber format: RS274X FlatCAM version used: 2354116e377976743369e37483c87f56aebbe86a Labcenter version: 8.1

Feel free to ask for more informations and/or to try fixes on my machine.

Best regards, Jean-Sébastien
