There's no actual error or problem, but it's just poor coding practice.

It's a static non-trivial type. We avoid those in Qt, so I make the 
recommendation to everyone, everywhere.

Static non-trivials imply a load-time and exit-time overhead, even if you 
never use that variable again. Better to initialise on first use and make sure 
you really need to cache the result.
