[Evolution] opening up attachments

[Aquatic Safaris Diver <diver aquaticsafaris com>]

I'm using evolution 2.8 and having problems with opening attachments.
The helper application will say that the file cannot be found.  It seems 
that evolution is sending 
~/.evoltuion/cache/tmp/evolution-tmp-p0AhdW/AQ_Invoice%23DW53038001.pdf 
to the application, but actually saving the file as 
~/.evoltuion/cache/tmp/evolution-tmp-p0AhdW/AQ_Invoice.
The attachment in the email is AQ_Invoice#DW53038001.pdf
It looks like evolution is not dealing with the # character correctly.
Thunderbird, mozilla email and the older evolution does not have this 
problem.

Thanks for any help,
Paul
