[Python-modules-team] Bug#922467: Noise from wkhtmltopdf ends up in the process' stdout/stderr

[Enrico Zini]

Package: python3-pdfkit
Version: 0.6.1-1
Severity: normal

Hello,

thanks for packaging pdfkit.

In the current buster, using pdfkit results in noise to the program's
output streams:

$ cat /tmp/foo.py
import pdfkit

pdfkit.from_string("foo", "/tmp/test.pdf")

$ python3 /tmp/foo.py
libpng warning: iCCP: known incorrect sRGB profile
libpng warning: iCCP: known incorrect sRGB profile
Loading page (1/2)
Printing pages (2/2)                                               
Done                                                           


This is unfortunately almost a showstopper for using pdfkit on command
line tools.

Enrico
