Thanks for reporting this!
I can confirm this in the internal version 2010.12-9 also when opening it
directly in Calendar app instead of saving it first.

I stumbled over this bug yesterday when trying to import some hand-crafted .ics
files.

After some playing around I think I found the cause:
The import chokes if a VEVENT has DTSTART and DURATION set. It works perfectly
if I add DTEND to each VEVENT. [0] (With or without DURATION.)

IMO this is a violation of RFC 2445 [1] which says, in my understanding, that
both DURATION and DTEND are optional; 4.6.1 also explains when events without
those fields are supposed to end.

[0] In the example from this bug report:
perl -pe 's/^DTSTART;(.*)/DTSTART;$1\r\nDTEND;$1/g' schedule.en.ics >
schedule.end.ics
