Committed with rev 47255.
You'll find the workaround (surrounded by the IFDEF LCLQt) + some added 
Debugln + a minor fix (a ShowHint := true was missing) + an attempt to 
use a different code for moving tabs (surrounded by an IFDEF 
USE_PageIndex). It doesn't make any difference but it saves a number of 
tests, because they're done in LCL. You may keep it or throw it away 
following your taste.

I hope you'll have better chance than me. I tried with a small test 
application, but no way to reproduce the bug. Tabs were always 
inserted/moved properly.
True, I did use just standard components i.e. a standard NoteBook with 
standart TabSheet, and my tabs didn't come from a StringList, but I 
don't see how this should make a difference. The Qt code involved was 
exactly the same, as far as I can tell, and my debugln's tell.
