Bug#973910: gpsprune: When tile cache "root" doesn't exists there is no error message but no bckground map either

[Peter Gervai]

Package: gpsprune
Version: 20-2
Severity: minor
Tags: upstream

The cache was created in a directory which got cleaned [full of temporary stuff].
gpsprune cache directory was removed, too. 
gpsprune don't warn the user at the start but due to missing dir it cannot retrieve
background map tiles and cannot display them, which is very confusing.
I had to strace it to see that file creates fail with "no such file or directory".

The user shall be warned, I would say.

Thanks!
