[Qgis-developer] QGIS 2.10.1 Pisa - Read CSV file problem

[Zoltan Szecsei]

Hi,
Fine - I did ask for an opinion, and I got one :-)

The CSV files are from South Africa's 2011 Census - as put out by 
StatsSA, and exported from SuperCROSS.
In this particular file, the numeric field names are for the "Age last 
birthday" of the occupant. (yep, from 0 to 120!!!)

So in short, I guess there are many, many users of this data - and for 
me an unnoticed error/deficiency, is still and error/deficiency.

Whilst I am not too perturbed because I can get around this issue, I 
figured it was my "civic" duty to raise it.

Cheers for now,
Zoltan
