OK, and here I am telling you that there should be no issues... and you find one :-P Actually Qt did not change anything, it seems that the chrome engine in it did. We had a similar issue with kf5-messagelib: <https://salsa.debian.org/qt-kde-team/kde/messagelib/blob/master/debian/ patches/fix_webenginemessageviewer_with_qt_5_11.patch> Although I don't think that's exactly related. I must admit I have no idea about the web stuff in Qt, much less about the python stuff. You might want to ask in interest@qt-project.org I don't know if some other team mate here can't help either :-/ I wished I could do more here, but sadly not now :-( Cheers, Lisandro. -- Only wimps use tape backup: real men just upload their important stuff on ftp, and let the rest of the world mirror it ;) Linus Benedict Torvalds.
