__Description:
When adding a custom code completion database for a project from an include folder, one specifies "Recursive" and the folder contains a symbolic link to itself, then the folder seems to be recursed over and over ad infinitum.
This happened to me when I tried to import the directory "/usr/include/GL/", which for some reason contained a symbolic link "/usr/include/GL/GL -> /usr/include//GL"

__Symptoms:
CPU, memory & swap usage go to pretty much 100%.
the progress bar and thus the whole dialog window keeps getting wider and wider... pretty weird-looking effect... ;-)

__Exact steps to reproduce the bug:
go to "Project" Menu
-> "Project Options"
-> "C++ Specific"
-> "Code Completion"
-> "Add..."
select "Custom Directory PCS Importer"
-> "Next"
add a directory containing a self-referencing symbolic link
select "Recursive" check-box
-> "Next"
