Bug#1107830: unblock: gtk4/4.18.6+ds-2

[Simon McVittie]

Package: release.debian.org
Severity: normal
X-Debbugs-Cc: gtk4 at packages.debian.org
Control: affects -1 + src:gtk4
User: release.debian.org at packages.debian.org
Usertags: unblock

Please unblock package gtk4

[ Reason ]
New upstream bugfix release

[ Impact ]
Several bug fixes, including crashes.

[ Tests ]
My GNOME desktop continues to work normally (tried various apps 
such as GNOME Software, GNOME Settings, Nautilus).

The test suite still passes at build-time and as an autopkgtest, 
including new test coverage for the gsk/gskpathparser.c changes.

[ Risks ]
Key package, central to our default desktop environment.

This particular upstream has not always been as strict as we would like 
about bugfix-only changes in micro releases, but in this case the 
changes seem to be narrowly-targeted. The noisiest changes that affect 
production code are those in gsk/gskpathparser.c, which fix parsing of 
some SVG symbolic icons; there is new test coverage for these in 
testsuite/gsk/path-special-cases.c.

The change in gtk/a11y/gtkatspicontext.c is to fix AT-SPI spec compliance, 
but could conceivably cause accessibility tools to regress if they were 
relying on the previous, non-spec-compliant D-Bus signal names 
"activate" and "deactivate" (D-Bus signal names are case-sensitive, and 
the correct names start with a capital letter).

The changes in gtk/gtkimcontextwayland.c and gtk/inspector/ are noisier 
than I would normally expect for a stable release, but are only relevant 
when using GTK's built-in "inspector" debugging tool (press Ctrl+Shift+I 
while running a GTK 4 app), and are inactive in normal use of GTK.

Changes in demos/ do not affect production code, only gtk-4-examples.

Changes in gdk/macos/ are not compiled in Debian.

[ Checklist ]
  [x] all changes are documented in the d/changelog
  [x] I reviewed all changes and I approve them
  [x] attach debdiff against the package in testing
      (lightly filtered to exclude translations and irrelevant changes)
