Description Jonathan Pobst 2012-04-22 19:58:15 UTC
Pinta runs successfully under the last Mac version of Mono built by Novell: 2.10.2.

Beginning with 2.10.3, running Pinta results in:

(Pinta:1929): Gtk-WARNING **: Could not find the icon 'gtk-dialog-error'. The 'hicolor' theme
was not found either, perhaps you need to install it.
You can get a copy from:
GLib.GException: Icon 'gtk-dialog-error' not present in theme
  at Gtk.IconTheme.LoadIcon (System.String icon_name, Int32 size, IconLookupFlags flags) [0x00000] in <filename unknown>:0
  at Pinta.ErrorDialog.Build () [0x00000] in <filename unknown>:0
  at Pinta.ErrorDialog..ctor (Gtk.Window parent) [0x00000] in <filename unknown>:0
  at Pinta.MainClass.ExceptionManager_UnhandledException (GLib.UnhandledExceptionArgs args) [0x00000] in <filename unknown>:0
  at GLib.ExceptionManager.RaiseUnhandledException (System.Exception e, Boolean is_terminal) [0x00000] in <filename unknown>:0 

The issue is still present in Mono 2.10.9.

IIRC you should use Widget.RenderIcon if possible as that falls back to the GTK+ builtin stock icons if the theme doesn't have the icon.
