Erroneous Message with Load File UI on IOS

[k8macarthur]

I've noticed over the past few weeks that when I ever I used:

s=hs.load()

Such that a window opens up to allow a file selection. After file selection the following pop-up occurs. Given that this is during file load there is no chance of overwriting the file. I normally ignore the error but it occurs to me to it not ideal and might concern new users.

This should be fixed in #38.
It may be related to changes in traits/traitsui, do you know if this message has been there for a long time or this is something recent?

@ericpre great! Sorry I'm really not good enough with UI errors to fix this myself. I think the error has been there for some months now. I can't quite remember when it changed.

It seems that this bug have been there for a while: enthought/traitsui#1658 and this is why I was curious if you could remember when it started to appear, as it could help to figure out when the regression was introduced. For information, #38 is a workaround for this bug, and the original bug still needs to be fixed in traits/traitsui.
