From 2a458061b162780cba638ce224a7ba674f151115 Mon Sep 17 00:00:00 2001 From: Matthew Jordan Date: Wed, 30 Jan 2013 14:15:27 +0000 Subject: [PATCH] Fix memory leak in res_calendar_icalendar The ICalendar module had a systemic memory leak on each fetch of data from the ICalendar source. The previous fetched data was not being properly disposed. This patch makes it so that before each fetch of data, we dispose of the previously fetched data.
