@kewisch Should I resolve the conflicts (by rebuilding) or will you do this anyway before merging?

PS: Maybe this could be automatised via Travis.

I made this issue my start page. How many trees may I plant to get the fix implemented?

[Nemental]

@giddyhup I feel you! :D

@kewisch please include this!

This looks good, thanks so much! I've added another test for iCalendar. I'm not sure if it is technically allowed to have multiple parameters there, but at least we'd be able to read them.

I hope you planted a lot of trees. If so, not getting around to this may have been my easiest contribution to save the planet yet ;-)

Thanks for merging. Indeed it is allowed:
