           Summary: A crash and two bugs in the Classes view
           Product: kdevelop
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: gideon
        AssignedTo: kdevelop-devel at kdevelop.org
        ReportedBy: amantia at freemail.hu


Version:           cvs (using KDE Devel)
Installed from:    Compiled sources
Compiler:          g++ 2.95.3 
OS:          Linux

Hi, a crash and a bug in the Classes view.

The bug:
After manually editing a class method declaration
in the header file (like the return type of the method)
and save the file, the Classes view will show two more
times all the elements (methods/attributes) which are
below the edited line. So if you have an attribute "name",
you will see it 3 times after the first save, and 5 times
if you edit once more the class.

The crash (and a releated bug):

static KURL::List allFiles( const KURL& path, const QString &mask);

like methods (the "::List" is the important part) do not appear in 
the Classes view. More, if you try to
edit (e.g remove the ::List, but you can do anything) and save 
the header file, Gideon will crash with the attached backtrace. 
You can test it with the quanta/quanta/qextfileinfo.h (and .cpp)
from the kde cvs.
