When making a chart with constant value error bars, the error bars can only be of integer length. Decimal values are rounded to the nearest integer when entered. It should be possible to use decimal values.
To reproduce this bug:
1. Make a chart
2. Insert->X Error Bars... (or Y Error Bars...)
3. Click 'Constant Value' for Error Category
4. Under Parameters and Positive, type '0.5'.
5. Try to enter a value for Negative.
6. The Positive value should now have changed to '1'
(I'm using Debian's LibreOffice 4.1.5-2+b1 package)
For anyone else experiencing this problem, until this bug is fixed there is a workaround.
1. Fill a column with the desired decimal errors.
2. Under the error bars menu, select "Cell Range".
3. Enter the range of cells you just created (e.g. $Sheet1.$A$1:$A$10 )
4. LibreOffice should make the error bars the decimal length.

Is it possible to backport the fix in the 4.3 branch?

It is - I've just requested a code review. But it doesn't really help you w/ the other bug 78048
Now cherry-picked to -4-3: http://cgit.freedesktop.org/libreoffice/core/commit/?h=libreoffice-4-3&id=38f6065b0272ae4bc80f5f35866012b4ea0bc38b
