Control: tags -1 confirmed Looks like sip4 (4.19.14+dfsg-1) broke the SIP bindings again.
It's quite unfortunate that the 2.18.x LTR is EOL upstream, making them unlikely to provide a fix. I'll see what I can do to fix this. If I can't, we'll just have to release buster without QGIS and deal with lots of upset users.
