Strange `Errno::ENOENT` of ARGV value

[adam12]

I'm not sure how to even start debugging this one. I thought it was related to console being an overused term and perhaps the filename conflicting, but I'm not sure that's the reason (hence you see console2 as I try to identify if it's the cause).

It could be application specific and I haven't been able to reproduce it outside of my app.

It's not obvious, so here's my text input (I'm never at the Y/n prompt to provide input):

Attached are script output and timing, if it helps. Use scriptreplay --timing timing.txt script.txt to replay.

Actually, looking at it again, I wonder if it thinks that my ARGV is arguments to rdbg for remote socket. Here's a simpler command to reproduce.

This is using latest master.
