fitted line map caused crash

[SaOgaz]

Does this go in the specviz repo?

During a test session with @bethanjames, testing out the fitted line maps over some MUSE data, cubeviz crashed. Here's the trace back. Apologies for the bad formatting, can't seem to get it to look nicer.

@SaOgaz Please open a ticket in specviz and link it back to this ticket. Let's leave this open, for now too, though.
