Using KFileDialog::getSaveFileName(), there is a checkbox allowing to auto add extension to your filename when saving.

But KFileDialog does not add the extension even when the checkbox is clicked. This is a regression caused by commit 861225:
"Merge branch 'kfilewidget'"

http://websvn.kde.org/trunk/KDE/kdelibs/kfile/kfilewidget.cpp?r1=860118&r2=861225

which removed the call to appendExtension. The patch below fixes the issue, but not sure it's the best way of doing it...

regards
