ERROR: UndefVarError: `A` not defined in local scope

When trying to parse two csv files, I get this error:

tbl = CSV.File(files)
ERROR: UndefVarError: `A` not defined in local scope
Suggestion: check for an assignment to a local variable that shadows a global of the same name.

Some type information was truncated. Use `show(err)` to see complete types.

The files are mounted on an external hard-drive, but if I copy them locally, then everything works. Both files have empty last rows in them. If I delete those empty rows, then parsing "even" the mounted files works...

So strange...

Not sure why its complaining on the scope of that A variable, maybe due to some lazy step in ChainedVector...?
