Bug 54232

Version:           kdevelop-3.0a3 (using KDE KDE 3.1)
Installed from:    Compiled From Sources
Compiler:          gcc 3.2 Reading specs from /usr/lib/gcc-lib/i686-pc-linux-gnu/3.2/specs Configured with: ../configure --prefix=/usr --enable-threads=posix --enable-shared --disable-checking --with-system-zlib Thread model: posix gcc version 3.2 
OS:          Linux

1. Open kdevelop in IDEAL, no project is opened,
2.  Click on sidebar "Documentation", highlight any docuement e.g GTK, 
3.  Click on "Cutomsize the selected document..." icon, then kdevelop crashed.

Iif you have opened a project, this icon button works fine, I guess the problem is in DocTreeProjectConfigWidget::readConfig()  is trying to reference m_Project object which is null (because you have no project opened).

Problem cpp and line
The constructor DocTreeProjectConfigWidget calls readconfig() function but 
parts/doctreeview/doctreeprojectconfigwidget.cpp:void DocTreeProjectConfigWidget::readConfig()


The core dump info.
