The property
```
colorLink = "";
```
inside
```
class Attributes
{
align = "left";
color = "#ffffff";
colorLink = "";
size = 1;
font = "RobotoCondensedLight";
};
```
causes some rpt spam because it's empty by default. Setting it for example to
```
colorLink = "#ffffff";
```
fixes the issue.
Solution: Base class of ctrlStructuredText should have some color defined by default.
