Subject: [PATCH] gtk/icon-theme: Handle lack of SVG loader gracefully
|
|
|
c758dd |
|
|
|
c758dd |
When loading a SVG icon from a gresource file only containing SVG icons,
|
|
|
c758dd |
but without having a SVG loader available in gdk-pixbuf, we would crash
|
|
|
c758dd |
when trying to eventually load the resource. Fix this by gracefully
|
|
|
c758dd |
handling this by simply failing to load the icon, while the first time
|
|
|
c758dd |
it happens, log a warning.
