Review request for KDE Edu.


Repository: parley


Description
-------

When path to theme cache file does not exitst (e.g. after a fresh
installation) it is not created automatically which caused the
following error to be shown on stderr while reading and writing:

"QIODevice::read (QFile, "/path/to/theme/cache/startpagethemecache.bin"
): device not open"

Automatic creation of theme cache path is added. Location of cache file
is moved to QStandardPaths::CacheLocation.

Because for me it looks like that the theme image cache is what its name shows, a cache. I think that it's better to store it at QStandardPaths::CacheLocation rather then QStandardPaths::DataLocation.
