Bug 418085

Falkon works fine with up to date libraries. This is a distro issue

As I stated under Bug 396024, the extension JavaScriptButton caused failures in Falkon after updating several libraries to the newest version.
Therefore I disabled it, but now I am getting errors "Failed loading page; Something went wrong while loading this page; Try reloading ..." and a "Reload page" button. This occurs when I log out of an gmx.net account.
I never experienced that before, so it must come from the updated libraries.
As I said, I am very happy with Falkon and thank you for your work and would appreciate, if you could contact Texstar of PCLinuxOS and make Falkon work again.
Thanks,
Horstl

What Qt version are you using?

> What Qt version are you using?

According to "Help, About Qt" in Falkon:
This program uses Qt version 5.12.7.

Update to this qt-version took place on
Fri Feb 14 16:40:42 2020

With the same update I got these updates
python-rpm (4.8.1-11pclos2020) to 4.8.1-12pclos2020
python3-pyside2 (5.12.2-2pclos2019) to 5.12.6-1pclos2020
python3-shiboken2 (5.12.2-2pclos2019) to 5.12.6-1pclos2020
which may have to do with the problem of extension JavaScriptButton

For Python extensions you might be affected by this bug.

PyFalkon is almost entirely generated by shiboken2, and the mentioned error in the buf seems to be related to shiboken2 rather than Falkon itself.

There could also be some backported "fix" in Qt which broke some things.

For the error about "work with current libraries",
I have Artix here and it works just fine, there are even newer libraries than on PCLinuxOS.

Please have a look at https://www.pclinuxos.com/forum/index.php/topic,151685.15.html
Here (at Reply #23) Tex explains what problems he has with Falkon and libraries
Thank you!

This is already fixed, only thing missing is to release new Falkon version.
You can patch your distribution version with

And this is nouveau fault, you can find many bugs regarding this here.
