When launching vmprof --web from python 3.4 you get ``TypeError: Can't convert 'bytes' object to str implicitly`` exception

[jbzdak]

Stacktrace attached at the end of issue.

Problem lies in upload.upload function, that contains, where val variable is a bytes object, that is concatenated to string objects.

To fix this you'll need to encode it:

 val = res.read().decode('ascii')

Traceback:
