Description

If you run a fit that fails to converge, then try to change the fit engine to either DREAM or Differential Evolution.

To reproduce:
1) Load the dataset test/1d_data/latex_smeared.xml
2) Send latex_smeared.xml [1] to the fitting perspective
3) Choose the sphere model
4) Check all parameters for fitting, and set radius to 2000
5) Click fit, after a few seconds a message will be logged saying that the fit failed to converge (Note: this error doesn't appear in the UI #924)
6) Go to Fitting → Fit Options and choose DREAM or Differential Evolution
7) Click Fit

The attached error message is shown

This has everything to do with how dxl and dxw data are loaded in. I've added a fix for this to ​PR94.

In 590b5c2d6751d6e04e3b397709a0afb2df05d119/sasview:

Load dxl and dxw data in the same way x, y, dx, and dy are to ensure array lengths are the same. refs #994
