Comment 18 for bug 330117

Program: Libreoffice-impress 1:3.5.3-0ubuntu1 (as per the apport data) - hmm that apport data says it was 3.5.2 - and help shows 3.5.3.2 which is rather confusing.

To replicate the issue, move your cursor over the text '2nd level', double click (2nd level should now be shown in inverted text), now hit shift-tab.
For comparison, if I hadn't saved as a ppt it works (e.g. open impress, Click the layout with non-centred text is easiest - e.g. for me that's labelled 'Title centred' - left one on the 2nd row down of layouts), type Hello, hit return, type goodbye, double click to highlight the Goodbye, hit tab indents and changes the bullet, shift-tab unindents and changes the bullet back - as it should do.

So this does seem specific to something that has gone through the .ppt filter - whether it's created originally in libre or come from MS Ppt.
