Description Gökçen Eraslan 2010-09-24 07:45:17 UTC

Version:           unspecified (using KDE 4.5.1) 
OS:                Linux

When I try to import kde-networkmanagement project to see the UML diagrams about the project, Umbrello freezes and begins to use 100% CPU.

Reproducible: Always

Steps to Reproduce:
1- Checkout NM code from http://websvn.kde.org/trunk/extragear/base/networkmanagement/. Also you can find the snapshot of the code here (http://cekirdek.pardus.org.tr/~gokcen/files/networkmanagement-umbrello.tar.bz2)

2- Open Umbrello, follow Code -> Import Project
3- Select the networkmanagement directory that you just checked out
4- Answer questions as, Namespace, Namespace, Class, Class, Namespace, Namespace, Class
5- The last file imported is applet/interfaceitem.h and then it freezes.

Actual Results:  
Umbrello freezes.

Expected Results:  
Umbrello should import the project successfully.

I'm facing the same issue. Umbrello crashes when I import headers and freezes when I import C++ project.

This has been detected on FreeBSD (KDE 4.5.1) and openSUSE (KDE 4.5.2)

Still happening 1 year later

I'm using KDE SC 4.7.1 on archlinux.

I've attached gdb and seen that there is a 87-frame stack:
