Yes I agree to go for a.

Thanks for taking this up.

Ingo: I have now assigned this to you. If you can explain why my fix is required in a way that upstream would accept the change we should try to get this into KConfigWidgets proper. But I do not think that I can convincingly explain why it is required or what happens here.

After some debugging and reading the code I did not find any way that the KSharedConfigPtr could be accessed when it was NULL. It is never saved in a member variable. The only place it was saved was in the static thread_local variable of defaultConfig in kcolorschemehelpers_p.h. Since this was irritating because I understood QExplicitlySharedDataPointer to already handle thread_local ness

So after updating to latest kf5 this still happens. The windows event log tells me that the crash occurs from libkf5configwidgets.dll
Does not seem to happen on Linux, i have run it with valgrind to and only found other crashes on linux shutdown when closing the window.

Sorry, yes I meant the Certificate Dump not the Details.

We have even released 4.0.2 now.

JW-D with Gpg4win-4 we have support for multiple readers and also a dropdown menu for selecting reader ports. This should resolve this issue.

When we want to add more smartcards we should open new issues. This one is resolved.

I am closing this as the group support for gpgol is now in T5967

Still needs testing as this is a default off feature.

This needs to be tested with group configuration even for non mixed mode. There is an important wish to have the kleopatra group configuration be used in the keyresolver from outlook.

This can be bypassed by entering the date manually, was reported by a customer and I have just confirmed this.

Tested

Uhm. This enabled the button always in VS-NfD mode. Fixing.
