code analysis output doubles in editor and tooltip

When using code analyzer during editing and execute analysis under debug, then

• the anotation in the editor window is duplicated,
•  there are two warning singns, and
•  the tooltip over the warning sign show the same message twice.

Reproduce:

Use the wizard to create a new qt console application.

Way for the analysis warning on the a.exec() line.

Here without analysis run in debugger:

And now after "analyze current file":

same with tooltips:

The duplication in the tooltip is probably the consequence of the duplication in the warning signs on the border...
