This was only a real problem in one of the beta release of Qt 4.6, where they 
made the mapping fail fully in such a case. But at that point I made the 
fallback work properly, so even if the mapping fails, KDevelop keeps working.

But in the final release, they're turned the problem into a pure warning, so 
it's only an aesthetical problem.

And btw. the main problem is anyway that their check is somehow broken, as we 
actually _do not_ map a file beyond its size.

So to make it short: This issue is probably not the reason why your duchainify 
doesn't work.

Greetings, David
