Description of problem:
Every time my machine loose the connection with the mail server for some reason
(vpn drops, or even clock skew when trying to auth with GSSAPI and thus auth
fails) evolution leaks about 12 filesdescriptors.

ls in /proc/<num>/fd reveals they are all pipes.

Version-Release number of selected component (if applicable):
evolution 2.12.3

How reproducible:
always

Steps to Reproduce:
1. cause a forced disconnection through a network error

  
Actual results:
App leaks descriptors until they finish and app craps out.

Expected results:
No descriptors leaks, app should close unused descriptors.
