I note that the version shown is the master branch HEAD. I tried this and stable-2.11 using ubuntu 16.10 and Qt 5.7.1. I could not reproduce this problem.

I'm unable to reproduce with the same revision on Gentoo Linux using Qt 5.7.1 as well.

I'm on Arch Linux.

In doing some debugging, it appears that BtAboutDialog::linkClicked does not get called for that link, but does for all others in the about dialog.

Please disregard my comment about not able to reproduce. I misunderstood the issue late last night. I can now reproduce.

Clicking on the "More info..." link should open a new "About Qt" dialog window instead of changing the contents of that HTML view widget. Instead it seems to switch the HTML view to a blank page. Maybe related to the switch from QWebView to QWebEngineView. It seems that the BtAboutDialog::linkClicked slot does not get called at all.

QWebEnginePage only works with links beginning with http, https, and ftp. We used a url of "about:qt".

QWebKit and QWebEngine were both broken for different reasons. Fixed and tested with Qt 5.5, 5.6, 5.7, and 5.8. Closing.
