[New-bugs-announce] [issue12867] linecache.getline() Returning Error

[Jordan Meyer]

New submission from Jordan Meyer <jordanmeyer1991 at gmail.com>:

In trying to use the linecache.getline() function to extra data from a plain-text database format that I'm building. Every time I make a call to it (even from the interpreter directly) I get an error like the one below. I believe the problem lies in the linecache module itself.

Traceback (most recent call last):
  File "/Users/jordanmeyer/Documents/Python/eFlashcard/alpha/0.1a2/eFlashcard_0.1a2.py", line 59, in <module>
    eFlashcard_main()
