[PATCH] accounts.py: Print the stacktrace via traceback module

[Sebastian Spaeth]

All other instances were converted to format crash output including a
stacktrace, but this one seems to have been left out. Make Exceptions
print their stacktrace here too.

Somehow this one did not converted as all the other instances did.
patch applies to master. Noticed this with the latest gmail error that
was reported.
