Open the "Project Options" dialog, and scroll down to the "Run Options" page. 
Have you entered a working directory into the working directory field? If 
not, try adding the root directory of your project to that field (in your 
case the directory to add would be "/home/shane/workspace/neatl") and see if 
that allows gcc to find the sources.

If that works, you should probably file a bug on bugs.kde.org saying basically 
the same thing that you say in this email: that the gdb integration doesn't 
add the project's source directories to gdb's list of directories to search  
in for sources when setting breakpoints.

Thanks
