finders.py:148:__call__:ValueError: invalid literal for int() with base 10: ''

[rallenh]

Hi,

I regularly get "ipython quit unexpectedly" in the Fedora Problem Reporting tool (abrt).

Here's the reason:
finders.py:148:__call__:ValueError: invalid literal for int() with base 10: ''

Here's the backtrace/traceback:

Traceback (most recent call last):

To 'fix" this so that I don't get alot abrt notifications:
