Steps to reproduce:
1. Load village_points.shp and the 'By Village' layer in the excell table v4_CAM_HeadCount_MotherTongue_Multilevel_Census2008.xls (both available in issue #7271)
2. Join the .xls to the village_points.shp via the village_points VILL_CODE column and the .xls Code_Phum_STRING column
3. Go in village_points symbology property, and select Graduated
4. Select joined column 'By Vllage_Chaaraay'
5. Select 'Equal Interval' mode, with 5 classes

What you'll get is 5 classes with interval 0.00000 - 0.00000.

The modes I see as broken with joined columns are:
- Equal Interval
- Pretty Break

The modes I see as working with joined columns are:
- Quantile
- Natural Breaks
- Standard Deviation
