Summary	0003025: Unhandled unknown exception caught in GUIApplication::notify when opening file + memory leak
Description	This exception is encountered when opening the attached file. As a result nothing is visible in the display. I have been able to make the object display again by selecting all objects that are part of the cut and selecting 'View->Visibility->Show Selection', but this is not consistently reproducible. This file opens and displays fine in earlier builds (eg 10291)
Steps To Reproduce	Open the attached file. View the error in the 'Report View' window.

Kunda1 2017-05-11 03:08 administrator ~0008948	Please open a forum thread to discuss this with the FC community. Then bidirectionally link ticket <=> thread.

grandcross 2017-05-16 00:47 reporter ~0009027	Forum thread: https://forum.freecadweb.org/viewtopic.php?f=19&t=22470&p=174321 Also, some other visibility issues probably related... You can make the object visible by selecting the cut and hitting the space bar. However, if you try to edit a sketch, the display is empty. Similarly, if you delete the cut, the display is empty.

wmayer 2017-05-16 08:42 administrator ~0009028	The actual crash is fixed now. However, there is still a massive memory leak. When loading the project which only has 46 objects then around 200 DocumentObjectItem instances are created but less than 100 are destroyed when closing the document.

wmayer 2017-05-16 09:18 administrator ~0009029 Last edited: 2017-05-16 09:19	Add the test code into DocumentObjectItem::DocumentObjectItem `Base::Console().Message("Create item: %d, Object: %s\n", ++countItems, viewObject->getObject()->getNameInDocument());` and in DocumentObjectItem::~DocumentObjectItem() `Base::Console().Message("Delete item: %d, Object: %s\n", countItems--, viewObject->getObject()->getNameInDocument());` When reading the project the output is: Create item: 1, Object: Sketch Create item: 2, Object: Sketch Create item: 3, Object: Revolution Create item: 4,

Kunda1 2017-05-22 18:42 administrator ~0009086	Fixed by wmayer. Closing.

wmayer 2017-06-01 08:03 administrator ~0009236	Although the originally reported bug is fixed, the report revealed a memory leak in the new tree view implementation which still needs to be fixed.

Kunda1 2017-06-27 11:21 administrator ~0009558	Made this issue a PDN blocker due to remaining memory leak

Kunda1 2017-08-21 11:21 administrator ~0009979	@kkremitzki do you have a moment to take a look?

wmayer 2017-08-25 10:02 administrator ~0010006	The first part (fixed) of the crash could be considered as urgent but the second part with the memory leak is not a show stopper bug and can be degraded to normal priority. Furthermore it's not related to PDN at all but is related to the core system.
