Yes. I tried it now with revision 578829, same behavior.

That one is doesn't occur any more, thanks.

Hm, it is important, that you first click on the "Apply"-Button of the 
settings dialog and after that on "OK". Clicking on Apply takes one or 
two seconds. When I click on OK afterwards, it also takes a while, but I 
would assume, that this would come back immediately, because the change 
(renaming a category) are already done to the in memory database.
The same misbehavior is occuring, if you press the "Apply"-button twice. 
So it seems, that the internal todo-list is not cleared after pressing 
Apply.

OK, I had a closer look to the code now:

When Apply has been clicked, Settings::SettingsDialog::slotMyOK() will 
be called. There you make the changes on the DB::ImageDB::instance(). 
But I can see, where the CategoryItem* item 's _...Orig members are set 
to the now applied values. In my opinion you have to read the QListBox 
_categories again like you do in Settings::SettingsDialog::show().
