Version:           svn 1032389 (07.10.09) (using KDE 4.3.1)
Installed from:    Gentoo Packages

I received the following crash in this part of the code:

void BuilderJobPrivate::addJob( BuilderJob::BuildType t, KDevelop::ProjectBaseItem* item )
{
    Q_ASSERT(item);
    kDebug() << "adding build job for item:" << item->text();

I hit compile project while I had no targets set up.
