Version: 1.9.9 (using KDE 3.5.9) Installed from: Gentoo Packages Compiler: gcc-4.2.3 ppc OS: Linux there is no default icon currently for the toolbar button "Send Queued Messages Via". it should have the same default icon as the "Send Queued Messages" toolbar button.
This is fixed in KDE4, where it is possible to have icon fallbacks.
