Thanks for reporting. Could you post a simple program that generates this error?

hi - to WAR this issue i downgraded to 2.3.9. When i upgraded again i got into a mess with qt bindings so i ended up reinstalling a clean environment. Now i cant seem to reproduce the issue!

looking at _handle_stream() in Anaconda2\lib\site-packages\spyder\widgets\ipythonconsole\debugging.py, I cant see where reply gets assigned to before its referenced in line 136. Maybe this is just a rarely used path?

sorry thats all i can offer. Feel free to close

Thanks. In any case, I'll check if reply can go unreferenced before closing :-)
