Footprint Wizard 2D barcode issue

[ocb-hd-ccb]

I am trying to generate a 2D barcode (QRCode) with the footprint wizard and I get the following issues:

```

I get the same on the 5.1 branch I think, although the error is presented a bit differently. See attached screenshot.

I just installed 5.1.3 and it seems to work fine there (I was on a windows box)...

Here is something similar but different. I was able to get the qr-code gen to work on windows 5.1.3 but I would occasionally have a blank QR code exported from the wizard.

The above screen shots are from the https://kicad-info.s3.dualstack.us-west-2.amazonaws.com/original/2X/6/64a89af3831bec14132633e1c857281063552a53.py script. The wizard works fine but again the 'export' to the footprint editor doesn't have results.

I prefer the segno because of the micro-qr compatibility.

Setting to 5.1.6 as only critical bugs are allowed at this time for 5.1.5

[Nick Østergaard (nickoe)]

Mmm, isn't this critical when we get an exception?

[Seth Hillbrand (sethh)]

Hmm... My thinking was that this only prevented generating the QR code footprint with a specific plugin. If we can fix in Python, there's probably an argument to add this in to 5.1.5

[Seth Hillbrand (sethh)]

Turns out that this was Python3 specific (and two different bugs).

Both bugs were addressed in the python module.

@Wayne, how do you feel about sliding this into 5.1.5? The risk is low (python only) but this feature is only an add-on, so not critical function.

I just checked this in:
and it worked fine. I am attempting to add an external script for testing but I cannot find a way to add a custom directory location to the python search path...

Crap, this did not fix the segno footprint plugin...

[Wayne Stambaugh (stambaughw)]

@Seth, this one is fine to merge into the 5.1 branch. I don't see it causing issues other than the python script itself.

[Seth Hillbrand (sethh)]

@ocb-hd-ccb: You will need to report that to the author of the plugin.

[Nick Østergaard (nickoe)]

@Seth, thank you for looking into this as well :)
