OS:                Linux

namespace Meow {
#include "test.h"
}
int main()
{
printf("%d %d\n", x, Meow::x);
}

After the above, where test.h just contains "int x;", the syntax highlighter finds the non-existent variable "x", but doesn't find the actual existing variable "Meow::x".

This apparently breaks syntax highlighting when using "Eigen::VectorXd v;" (as opposed to "using namespace Eigen; VectorXd v;").

(Kdevelop version is 4.2.2, not 4.2.1, but couldn't select that when reporting.)

Reproducible: Always
