Crashes on start : NameError: name '_' is not defined

[Mark M Lambert]

Running on Ubuntu 12.10 64 bit
Version 0.5-0ubuntu1

When I run magicicada from command line it crashes with following output:

$magicicada
Traceback (most recent call last):
  File "/usr/bin/magicicada", line 36, in <module>
    from magicicada.gui.gtk import MagicicadaUI

Status changed to 'Confirmed' because the bug affects multiple users.

I just ran into this on 13.04 as well w/ version 0.5-0ubuntu1.

I guess there is the line

from gettext import gettext as _

missing at the beginning (~ line 30) in usr/share/pyshared/magicicada/gui/gtk/operations.py

Hi

I just added

from gettext import gettext as _

to

/usr/lib/python2.7/dist-packages/magicicada/gui/gtk/operations.py
/usr/lib/python2.7/dist-packages/magicicada/gui/gtk/listings.py
/usr/lib/python2.7/dist-packages/magicicada/gui/gtk/status.py

and the problem went away

I previously commented to attest the validity of Evandro's solution. After reinstalling and reapplying the fix, I noticed that it is very important where you place:

from gettext import gettext as _

in the three files. Initially I placed them too high and Magicicada would not start. So just for clarification, open each of these three files:

/usr/lib/python2.7/dist-packages/magicicada/gui/gtk/operations.py
/usr/lib/python2.7/dist-packages/magicicada/gui/gtk/listings.py
/usr/lib/python2.7/dist-packages/magicicada/gui/gtk/status.py

and add the line:

from gettext import gettext as _

to each of them, right after the line:

# pylint: enable=E0611

and that should work. This is usually right above any lines saying 'import magicicada ....' but also above another import in one of the files. I have tested that as long as 'from gettext import gettext as _' is after '# pylint: enable=E0611' and before any lines that say 'import magicicada ...' in all three files, that it works.
