Jupyter's R-kernel standard error output has line breaks after every character

[jolespin]

Sometimes an error window pops up but most of the time it just pops up in the stdout as each character separated by linebreaks

Here's my conda info

could you please give me the code in your notebook that leads to this error ?

I will try to reproduce it and forward to notebook group to fix it.

Thanks

[jolespin]

Yea, try just a simple error like: print "a"

[mingwandroid]

@csoja can you assign this to the best person to look into it? If it's something I've done wrong then I'd be glad to be advised where to begin investigating.

[csoja]

@mingwandroid I'm not sure who is the best person. Are you able to reproduce the error?

[mingwandroid]

Yeah, I've seen it, it's annoying rather than very serious which is why I've not spent time investigating it.

Unfortunately, I'm not going to be able to help w/ the troubleshooting b/c my R Kernel is broken in Jupyter :( #3316 (comment) . Luckily, I've found a way to use my version of R installed through conda to work on RStudio (details in my answer here http://stackoverflow.com/questions/38534383/how-to-set-up-conda-installed-r-for-use-with-rstudio)

[mingwandroid]

This is fixed now. I'm not entirely sure who or what fixed it though.
