Demonstration of bug
when sort (either ascending or descending) is selected it doesn't work.
Steps to reproduce:
1. open attached file
2. select sort from the autofilter dropdown (or sort from the Data menu)
two boxes of progress bar appear and then nothing happens - libreoffice freezes
data gets sorted
delete most of the data (although there is not a vast amount to start with)
Platform (if different from the browser):
Browser: Mozilla/5.0 (Windows NT 5.1; rv:14.0) Gecko/20100101 Firefox/14.0.1
[Reproducible] with "LibreOffice 18.104.22.168 German UI/Locale [Build-ID: e29a214] on German WIN7 Home Premium (64bit)
Reason for the problem is the comment in C5. When the comment has been deleted sort will work without problems
Problem seems not related to using Sort in filter dialog, I also see the Crash when I use normal 'Data -> Sort'
So this one is a DUP of "Bug 54018 - EDITING: CRASH sorting cells range with Comments"
