fixed up todlist to work again. The segfault resulted due a real ugly code-style:

Never, realy never, use "using namespace <...>" inside a include file.
Ever use "Opie::<class>" or such inside include files. Think twice, before using
a "use namespace <...>" inside a c++ file. If you're using it just 3,4 times,
write "Opie::<class>::<variable>" or such. If you just simple write a using
namespace all the time it makes the idea of namespaces obsolete. Mostly: just
integrate your OWN namespace (in that case use namespace Todo;) - but try
to use all other namespaces the explicit way - so you will sure that the compiler
inherits the right methods.
ToDo: write this statement into the developer wiki
