Comment 1 Ignacio Casal Quinteiro (nacho) 2010-04-04 14:34:59 UTC

I just tried with 2.30 and it doesn't crash, though gedit is not able to open the file as it contains invalid chars. So this should be marked as a dup.

Comment 2 Pedro Villavicencio 2010-04-05 12:04:36 UTC

Agreed, I'm not getting the crash on 2.30 either.
