Version:           svn (2007-05-24) (using KDE KDE 3.5.7)
Installed from:    Ubuntu Packages
Compiler:          gcc 4.1 
OS:                Linux

Using the latest svn checkout of the unstable digikam (2007-05-24), compile fails with gcc 4.1.  I have reproduced this compile-time crash three separate times (twice with unsermake and once with make).  All svn versions of required digikam libraries (checked out just minutes before digikam) compiled and are installed to prefix=/usr.  digikam(svn) is configured for prefix=/opt, but also fails with prefix=/usr.

Making all in dmetadata
