Error when loading QIcon from plugin resource on mac

Hi,

i have several plugins where i call a function to retrieve the plugins icon, for example:

Code:

QIcon MyPlugin::icon() {
return QIcon(":/images/picture.png");
}

When i load the plugin in the main application i still get an error:

Code:

The funny thing is that it works fine under Linux and Windows.

Could anybody say me what on Mac is going wrong?

Thanks in advance
