[Evolution] [evolution] Problem importing ICS files

[no_interest fastmail fm]

I have a problem making use of ICS files. I'm pretty sure that in Fedora
23, double clicking would open an import dialogue and everything went
smoothly. Now, the system tries to do something when I double click the
file, but fails. When I use the Evolution import tool, the filetype
selection is greyed out and 'stuck' on Outlook Express Personal Folder.
Anyone an idea what is going wrong?

Cheers,

Matt
