BUGHUNT MODE ON;

There is a lazy class load system, so no includes, \Application\DB is used 3 
times.
\Application\DB is not recognized(as every other classes in other namespaces, 
as was stated here: https://bugs.kde.org/show_bug.cgi?id=280985 (btw, 3 year 
with no fix...)), Application\DB is recognized but wrong.
I have made a supposion that the parser doesn't recognize the leading 
backslash, but...

If we directly include the file /Application/DB.php the thing work.
Obliviously, including tons of files just to get duchain working is not an 
option.

WTF? What kind of logic make it working then we leave just 1 backslash of 3?

Another two things:

1: Somewhere in duchain all the namespace names are being lowercased, while is 
PHP namespaces aren't always lowercase, moreover they're case-sensitive and 
"\Application" != "\application". I lurked inside the sources but I had no 
success. Maybe someone will be able to suggest where is that mysteriuos place?

2: Sometimes in the completion the same namespace appears more times...

P.S. Using Kubuntu 14.04, Kdev 4.6 from repos and then 4.7.2 from sources, but 
still the same bugs :(
