Dear Maintainer,

the update of the package from v. 2.46 to 2.48 includes a regression which
leads to a segfault when rendering a WebKitWebView in an Gtk3 offscreen window
created by calling gtk_offscreen_window_new().  This breaks, inter alia,
printing HTML messages from the MUA Balsa
<https://gitlab.gnome.org/GNOME/balsa>.

See <https://bugs.webkit.org/show_bug.cgi?id=291372> for a detailed discussion.
Please note that the bug affects both Bookworm and Trixie.

The bug has been fixed with commit
<https://github.com/WebKit/WebKit/pull/46494/commits>.  I could apply it (with
line offsets) to 2.48.3 and re-build the package on Trixie, which fixes the
segfault.
