Bug#350181: gedit: Tabulations are incorrectly displayed

[Guillaume Melquiond]

Package: gedit
Version: 2.12.1-2
Severity: normal

When a tabulation follows a letter and starts on a tab stop, it is not 
displayed. The column number correctly increases by 8, but no empty 
space is displayed at all. This bug does not happen at start of line or 
when the previous character is itself a tabulation. So most files are 
displayed correctly, but files that contain embedded tabulations are 
not.

To reproduce this bug, open a new file, type 8 letters (to get to the 
first tab stop), type tab, type a few characters more; they will be 
displayed next to the previous ones.

I tried reverting to Sarge gedit (and libgtksourceview) but it didn't 
fix the issue unfortunately. I'm not sure gedit ever displayed embedded 
tabulations correctly, but I would think it did.
