Fix it, then Ship it!




This is clearly a porting bug. The fact that currently the config option can't be set via GUI is a different issue, that should not prevent this fix from going in.


src/filewidgets/kdirsortfilterproxymodel.cpp (lines 79 - 81)
<https://git.reviewboard.kde.org/r/128574/#comment68643>

    Please use `m_collator.setNumericMode(m_naturalSorting);` instead. It would also take care of disabling the natural sorting, if necessary.
