From 0bf2d899d8c14f8f54aea57ceb3ffbb010e581fe Mon Sep 17 00:00:00 2001 From: Jeffrey Stedfast Date: Sat, 7 Dec 2002 18:44:46 +0000 Subject: Fix for bug #33295 2002-12-07 Jeffrey Stedfast Fix for bug #33295 * e-msg-composer-attachment.c: Change the parent_class to a GObjectClass pointer instead of a GtkObjectClass pointer. (e_msg_composer_attachment_edit): Ref the attachment object so that if the attachment is removed while it is still being edited, the attachment object will still exist and therefor foil the user's attempt to make Evolution crash when they close the properties dialog for this attachment. (close_cb): Unref the attachment object. svn path=/trunk/; revision=19053 --- composer/ChangeLog | 13 ++++ composer/e-msg-composer-attachment.c | 130 ++++++++++++++++------------------- 2 files changed, 72 insertions(+), 71 deletions(-) diff --git a/composer/ChangeLog b/composer/ChangeLog index ae0520d217..b5fe6fd3b6 100644 --- a/composer/ChangeLog +++ b/composer/ChangeLog @@ -1,3 +1,16 @@ +2002-12-07 Jeffrey Stedfast + + Fix for bug #33295 + + * e-msg-composer-attachment.c: Change the parent_class to a + GObjectClass pointer instead of a GtkObjectClass pointer. + (e_msg_composer_attachment_edit): Ref the attachment object so + that if the attachment is removed while it is still being edited, + the attachment object will still exist and therefor foil the + user's attempt to make Evolution crash when they close the + properties dialog for this attachment. + (close_cb): Unref the attachment object. + 2002-12-03 Jeffrey Stedfast * e-msg-composer.c (message_rfc822_dnd): Get rid of the unused diff --git a/composer/e-msg-composer-attachment.c b/composer/e-msg-composer-attachment.c index 0f7c06ff26..4e97e71a6e 100644 --- a/composer/e-msg-composer-attachment.c +++ b/composer/e-msg-composer-attachment.c @@ -31,10 +31,9 @@ #include #include +#include #include #include -#include -#include #include #include "e-msg-composer.h" @@ -47,13 +46,13 @@ enum { };
