Language locale isn't set properly (I think)

I have an MPEG file I want to burn to DVD, so I downloaded DeVeDe by doing the following:

Code:

---

sudo apt-get install devede

---

When that finished, I went to the KDE menu, went to Multimedia, and selected DeVeDe.

Nothing happened, the program didn't start.

So I opened up a terminal and type:

Code:

---

devede &

---

Here's the reply I got at the terminal:

Code:

---

Traceback (most recent call last):
  File "/usr/bin/devede", line 40, in <module>
    print "Locale: "+str(os.environ["LANG"])
  File "/usr/lib/python2.5/UserDict.py", line 22, in __getitem__
    raise KeyError(key)
KeyError: 'LANG'

[1]+  Exit 1                  devede

---

From reading that, I got the idea that the program was trying to read the value of an envionment variable called LANG, but that LANG wasn't set. So I tried this:

Code:

---

export set LANG=en
devede &

---

And here's the reply I got:

Code:

---

    return _setlocale(category, locale)

I tried setting LANG to other stuff like "eng", "en-us", "eng-us", but they all failed. However, if you look in the code box I posted just above, you'll see it mentions something about the "C" fallback locale. So I tried this:

Code:

---

export set LANG=C
devede &

---

And the program started! Wahey!

So basically it looks like BT4 PreFinal has a problem with the LANG environment variable.

EDIT: I spoke too soon. After the program starts, after you click OK to create a Video DVD, the program freezes and crashes. Looks like I'll have to boot into Microgay Windgay to use ConvertXtoDVD.
