Attributed Error when print Exception

[wantdrink]

Hi there,

When I use client.deleteVolume(name=volume_name) I encountered below failure.
I tried to find the root cause and found that it was because I want to store the exception into a variable in the catch block and the exception's str throw an exception.

code snippet:

try:
	cl.deleteVolume(name=vv_name)
except Exception as e:
	message = "failed to remove virtual volume, name=%s, error=%s. " % (vv_name, e)

Traceback (most recent call last):
