Thanks for that. Since that patch has been commited to 2.2.2
I've tried that. Evolution now parses the ics files OK but when
accepting a meeting request, evolution segfaults after a call to
camel_mime_part_get_filename.

I'm afraid I didn't have debugging symbols compiled, but the
backtrace is:

#0  0x293b8e38 in camel_mime_part_get_filename ()

[snipped]

I did a quick search for camel_mime_part_get_filename in
Bugzilla and didn't manage to find anything.

Maybe my installation of gnome is incomplete (I use a different
wm) as I can't see any evidence of a bug report being sent after
I get the error message "The Application "evolution has quit
unexpectedly. You can inform the developers of what happened to
help them fix it" with the options "restart" or "Close".
