TypeError during setting starting values

[Svennito]

Had the error

Traceback (most recent call last):
File "/home/sven/hippo/23/ginny/2_setup.py", line 133, in
editor.ifile = set_dataset_starting_values(editor,dataset,config_dataset)
File "/home/sven/hippo/23/ginny/2_setup.py", line 89, in set_dataset_starting_values
if not np.isnan(value):
TypeError: ufunc 'isnan' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''

Was caused by reading dataset.csv with both comma and space as separators leading to two extra columns. A message such as "processing dataset.csv for starting values" would give some sort of a hint for the user where to look for the cause?
