crash at adding symbol to schematic

Description

While adding subsequently symbols from the symbol-chooser into the schematic the complete kicad-application crashes and closes. The crash occurs not always, but with a high reliability.

The following settings seem to be important:

• after adding a symbol hit 1x ESC to end that symbol, but to keep the "add-symbol"-dialog.
• if one hits 2x ESC so that the cursor is in standard "selection"-mode than one needs to invoke the "add symbol"-dialog again - this seems to work without crash
• automatic annotation is ON
• annotation-modus seems to have no effect
• at bottom of symbol chooser both settings are checked (place repeated, place all units)

Steps to reproduce

1. open attached project, open schematic: crash_add_symbol_01.zip
2. setting: auto-naming of symbols: ON (left toolbar)
3. click "add symbol" button on right toolbar for symbol chooser --> symbol chooser opens
4. on bottom: check both settings (place repeated, place all units)
5. type "4302" to get IR4302
6. doubleclick at IR4302 --> symbol chooser closes, IR4302A-unit is attached to cursor. place IR4302A on eeschema-canvas
7. only 1x ESC to abort placing more units --> cursor is still in "Add Symbol"-mode
8. click on eeschema-canvas to open again symbol chooser
9. doubleclick IR4302 to add next IR4302 (again only unit IR4302A)
10. do some more rounds (step 6+7+8+9) with adding one unit -> ESC -> click to reopen symbol chooser -> add IR4302A-unit -> ....
11. after 2....5 units a crash occurs

It could be that there are two different crash-problems. sometimes the crash occurs at doubleclicking the IR4302-entry in symbol-chooser, sometimes the crash occurs after placing the new IR4302 at the canvas.
