Sanger alignment fails if path to files contains commas

Scenario:

1. Save sanger input files (e.g. from the "sanger" folder) to directory with commas "," in path.
2. Click "Tools" -> "Sanger data analysis" -> "Maps reads to reference..." and run sanger with files, saved on 1. Declare only one file with reads.
   Expected: If you run the same alignment with the same files, located in a directory with comma-separated paths in Workflow Designer, the alignment passes without any problems. This makes me think, that commas (or maybe some other special characters, I haven't checked them all) do not influence the alignment process itself (here I need to remind you, that when you run Sanger alignment with the above-mentioned dialog, it runs in a child process). Probably, the problem appears on some process-preparation step. So, I expect, that this scenario should passes well and without failures after the fix you'll do. 
   Current: "wrong output format"
