Test environment: Windows 7 64bit
Windows installer 3.2.20141205.1835
No important crashes or blocker issues found.
Fitting seems to work well on single-layer plots. But, as identified in #7903, it doesn't support plots with multiple layers.
I tried several function types and they all behaved well. Sequential fitting also seems to be working well. The following minimizers behave robustly even under rather pathological conditions and non-smart parameterization: Levenberg-Marquard, Simplex, Conjugate gradients, Damping, BFGS. FABADA seems to be a bit more weak, and it will often produce errors like "Convergence NOT reached after 499 iterations. Try to set better initial values for parameters:..."

Tested on Windows 7 64 bits, installer mantid-3.3.20150428.729
Found the following issues:
- Setting the Minimizer to Conjugate gradient (Fletcher-Reevers imp.) causes an unexpected exception. The same happens with Conjugate gradient (Polak-Ribiere imp.). Ticket #11643 has been created.
- SequentialFit dialog has an option, "Plot against log", that does not seem to be working. The output graph is empty although the table with fitting results is correctly populated. Ticket #11644 was created.

I have also noticed this issue:
- When selecting a polynomial fitting function with n=-1 (or any other negative value) an error message pops up indicating that n cannot be negative, but Mantid crashes afterwards (new ticket #11652).

This ticket has been transferred to github issue 7263
Opened straight to testing with a fake owner, so anyone can test.
