Bug Fixes in KDE Base
fix KMountPoint::List::findByPath() for non-existing file argument
dfaure says this is a porting bug because of moving from KStandardDirs
functionality to QFileInfo::canonicalFilePath(). The latter returns
empty if the file does not exist.
But this usecase is important for KIO::CopyJob: It wants to check the
available space on the target mount point.
