Bug#1059326: python3-reportlab: Can't set standard fonts

[Sebastien Delafond]

Package: python3-reportlab
Version: 3.6.12-1
Severity: normal

Control: notfound -1 4.0.8-1
Control: found -1 3.6.12-1

This is the same type of issue as archived bug
https://bugs.debian.org/1029683, and I'm filing this new one to make
it clear python3-reportlab in bookworm is affected.

Here's a short reproducer :

from reportlab.graphics.barcode import createBarcodeDrawing
barcode = createBarcodeDrawing('QR',value='test')
barcode.asString('png')

And the associated error :

,----

In case someone out there is stuck real bad with this bug in bookworm,
here's a very nasty workaround for which I of course decline all
responsibility:

$ mkdir /usr/share/fonts/type1/gsfonts
$ ln -sf /usr/share/fonts/X11/Type1/C059-Roman.pfb /usr/share/fonts/type1/gsfonts/n021003l.pfb
