[issue19879] imageop: bug in error handler

2013-12-03 Thread Matthew Bergin 

Matthew Bergin added the comment:

I am going to test it against 2.7 a little later on this afternoon.

I typically host all of the code I write at https://github.com/levle but atm 
the github repo I use to host the project is private. Once I work out some of 
the kinks I will set it to Public.
