Re: [ptp-dev] Abstract element viewer selection bug

[Nathan DeBardeleben <ndebard@xxxxxxxx>]

Clement.  This is more than acceptable to me - and I assume Greg as 
well.  You've correctly explained the problem, bugged it to Eclipse, and 
gone through a discussion with some people in the bug report as to where 
you see the bug.

I am fine writing it off right now as a Linux GTK2 SWT bug.

Thanks for taking the time to send in the bug report and explain it to 
me.  We can just wait until it gets fixed for Linux and until then tell 
our testers/users that this is a known bug that is outside of our problem.
