IconThemeSelector::ReturnFallback has a parameter const
std::vector<IconThemeInfo>& installedThemes. The code which calls this
method, passes there a reference to IconThemeScanner::mFoundIconThemes,
which dynamically filled with the themes found in the installation
folder. Now, it returns FALLBACK_ICON_THEME_ID (currently set to tango)
only if installedThemes.empty(), meaning that we couldn't find any icon
theme in the installation folder (including tango!). So normally, when
there is at least one theme installed, this "return
FALLBACK_ICON_THEME_ID" will never happen.
