Hi,

(0. Be sure, that Tools > Options > "... Calc" > View > Text overflow is activated)
1. Write text which is too long for a cell A1 and some text in the cell B1
(right to it).
2. Format cell A1: Alignment > "Wrap text ..." and Text orientation not 0
degrees (here as an example 90 degrees which I often use).

The text of cell A1 goes into the text of cell B1. Normally, there should be the
text overflow behaviour with the red arrow.

Maybe this is only a Ubuntu/Debian ooffice bug, but I guess it isn't. If it's
the case: sorry. Then, I will file it there.


Remarks:

* The red arrow isn't also shown if the "Wrap text ..." is deactivated.
* Text overflow works for example with orientation = 100 degrees (on the left side).
* Orientation > 180 degrees: the text is upon other cells somewhere to the right.


Cheers,
Dominik
