This WebKitGTK update causes a compatibility problem with older versions of Evolution when handling e-mail attachments. For this reason, fixed versions of Evolution have also been released along with this WebKitGTK update.

For the oldstable distribution (bookworm), these problems have been fixed in version 2.50.1-1~deb12u1.

For the stable distribution (trixie), these problems have been fixed in version 2.50.1-1~deb13u1.

We recommend that you upgrade your webkit2gtk packages.
