Description Kamil Dudka 2024-09-18 15:00:07 UTC

SUMMARY
If an HTML e-mail contains `<a href="https://..." target="_blank">...</a>` and I click on the link with the left mouse button, the link is not opened and the following warning from qtwebengine appears in the terminal:
> Can not adopt content from a different WebEngineProfile.

STEPS TO REPRODUCE
1. View an HTML e-mail with such a link.
2. Click on the link with left mouse button.

OBSERVED RESULT
The link is not opened and the following warning appears in the terminal:
> Can not adopt content from a different WebEngineProfile.

EXPECTED RESULT
The link should be opened with my default Internet browser.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Gentoo Linux default/linux/amd64/23.0/systemd
KDE Plasma Version: 6.1.4
KDE Frameworks Version: 6.5.0
Qt Version: 6.7.2

ADDITIONAL INFORMATION
If I click on the link with the right mouse button and then click `Open URL`, a new page is opened in my default browser as expected.

Comment 1 Kamil Dudka 2025-06-04 07:24:20 UTC

Still reproducible with kmail 6.4.1 using:
KDE Plasma Version: 6.3.5
KDE Frameworks Version: 6.14.0
Qt Version: 6.9.0

Comment 2 Markku Enäkoski 2025-06-06 16:28:18 UTC

I can confirm this happening. For some reason unknown to me, links can be opened by holding ctrl button while left clicking. This behaviour happens in both Wayland and X11 sessions.
Manjaro Linux x86_64
KDE Plasma 6.3.5
KDE Frameworks 6.14.0
QT 6.9.0

Comment 3 Kamil Dudka 2025-06-08 17:02:09 UTC

Yep, holding Ctrl while clicking on the link works.  Thanks for the tip!
