Very likely this bug exists since 2017 when support for promotion of local certifications to exportable certifications was added.

Fixed in gpgmepp for gpd5x. I think for VSD 3.3 we'll add a patch to gpg4win.

After further investigation it looks like this bug exists since quite some time.

The state machine in GpgSignKeyEditInteractor expects to see GET_BOOL sign_uid.okay and it should have answered with Y.

The dialog between gpg and Kleopatra looks like this:

[GNUPG:] KEY_CONSIDERED FADC4675146CFAF3D86F137E1D3C5E6E3DB3C71D 0<LF>
[GNUPG:] GET_LINE keyedit.prompt<LF>

[GNUPG:] GOT_IT<LF>

[GNUPG:] GET_BOOL sign_uid.local_promote_okay<LF>
Y
<LF>
[GNUPG:] GOT_IT<LF>
[GNUPG:] GET_BOOL sign_uid.okay<LF>

and then nothing else.

Fixed. If high-contrast is active then tool tips now use the same colors as buttons (e.g. white text on black for Kontrast No. 1).

With the above patch for breeze the toolbar and the configuration dialog title now also look correct in high-contrast mode.

The wrong/inconsistent coloring of the icons has been fixed.

After T7587: Kleopatra: High contrast mode isn't respected anymore was fixed this is what the buttons look like in Gpg4win 5:

Fixed. There are still some problems with the icons but those will be dealt with in a separate subticket of T6932: Icons, darkmode and stuff.

kleopatrarc, kleopatrastaterc, klanguageoverriderc, libkleopatrarc, and kxmlgui5/kleopatra/kleopatra.rc are now copied from the old location used by Gpg4win 4.4/VSD 3.3 (%APPDATA%/kleopatra) to the new location used by Gpg4win 5 (%GNUPGHOME%/kleopatra) if they do not yet exist at the new location. This is also logged.

It seems that High Contrast mode is completely ignored with Qt 6/KF6 (at least with Breeze and the built-in default style).

I noticed that the signing key B0D589D46708EC99 is a certify-only key. That signatures made with this key are dropped could be another regression of the fix for dkj's DoS bug.

The migration of the group config file works again.

Done.

Re-opening because I think rGaa36f6ae8bae needs to be backported to GnuPG 2.4 (see T7568). The fix for T7309 which introduced the regression has been backported to GnuPG 2.4.

I guess this is done if QT6 versions have a pinentry?
