From 2f8d9aacfa940af2c9424224c90ac2b77b0a4f58 Mon Sep 17 00:00:00 2001 From: Rob Bradford Date: Mon, 20 May 2013 12:09:20 +0100 Subject: [PATCH] shell: End grab if the grabbed shell surface has been destroyed The shell_grab_start function sets up a destroy notification on the shell surface such that when the shell surface is destroyed the pointer on the grab to the shell surface is set to NULL. We must therefore check whether the shell surface is NULL and end the grab if it is. https://bugs.freedesktop.org/show_bug.cgi?id=64689 --- src/shell.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/shell.c b/src/shell.c index f5d5bfff..72615702 100644 --- a/src/shell.c +++ b/src/shell.c @@ -1296,7 +1296,7 @@ busy_cursor_grab_focus(struct weston_pointer_grab *base) pointer->x, pointer->y, &sx, &sy); - if (grab->shsurf->surface != surface) { + if (!grab->shsurf || grab->shsurf->surface != surface) { shell_grab_end(grab); free(grab); }
