Review request for KDE Software on Mac OS X and KDE Frameworks.


Repository: kservice


Description
-------

After upgrading to Qt 5.7.1 I noticed that kbuildsycoca5 (and the "inline" version used by many applications) took long minutes to trawl a location where it's unlikely to find anything of interest among the probably huge number of files present: `/Applications`.

This patch avoids that by removing all occurrences of /Applications from the result of `QStandardPaths::standardLocations(QStandardPaths::ApplicationsLocation)` (and also removes any duplicates, which seems like a good idea just in case).

I've marked this "WIP" because I'm not sure how this implementation would work out for standalone app bundle builds. I *think* they should be fine even if installed somewhere under /Applications because `QStringList::removeAll()` should remove only entries matching "/Applications" exactly. Possibly the filter could be widened to catch all "*/Applications", meaning also $HOME/Applications. That should still leave, say, `$HOME/Applications/Kate.app`.
