SendCode / Rice triggering python exception

[pjcrosbie]

Hi. Here is a simple example of the errors I am seeing.

env:

• windows x64
• sublime & codesend, r-box
• rice from pip install
• python 3.6
• R 3.4.1

test_rice-02.R

library(feather)     
library(data.table) 

action and notes

• select all code in file test_rice-02.R

• ctrl-enter to send selected code

• ctrl-enter to send the selected code a second time (to trigger error)

• the first time I send the code, works OK

• rice prompt looks OK, i.e. I get r$> prompt so looks like it is ready for new input

• the second time I send the code, I get exception shown

• I can switch to console, press enter on last library(data.table) sent and processes OK

Trying different combinations of sending code can crash rice/conemu completely requiring me to kill process.

I have tried the same scenario plan R console and no issues.

Once I get the exception from the SendCode to rice scenario it is possible, but intermittently, to get same exception by just directly executing code in rice, i.e. without any SendCode use. However, haven't been able to get same exception by just starting a clean rice session and interacting directly with it, i.e. never use SendCode.

conemu/rice console output: this is the output from new clean rice session and using SendCode from sublime as described above

Actually, it was fixed earlier bcd344241fd21bab99b3ef2bfac80d4ffaec04ea.

EDIT: I was wrong.
