--- Comment #6 from ricardo filipe ricardo_barbano@hotmail.com 2009-05-08 07:01:08 --- you said the installer aborted but here it completed installation even without the patch, it wasn't a blocker. but it still was an exception so i'll send the patches anyways.
there was a guy on IRC the other day that had a problem with the same missing call and it was a blocker for him so i guess this isn't the only app affected.
