Subject: Initialize icaltimetype variables in Vcalendar's feed_fetch().
X-Git-Tag: 3.15.0~27
X-Git-Url: http://git.claws-mail.org/?p=claws.git;a=commitdiff_plain;h=3fd978a7ddc9d0f98bc1048f28ab527cfbf60ac6;hp=69ed24f94f81bd506b95dbc3cd858b842854c195

Initialize icaltimetype variables in Vcalendar's feed_fetch().

Also print out debug output if an event has no start or end,
as it can help determine why a malformed event file shows
weird times or duration.
