[Bug 1060171] Re: gtk-window-decorator crashed with SIGSEGV in g_hash_table_lookup_node() from g_hash_table_remove_internal() from event_filter_func() from gdk_event_apply_filters()

 

** Description changed:

  [IMPACT]
  
  destroyed_pixmaps_table leaking which may cause a chain reaction leading
  into a crash.
  
  [TESTCASE]
  
- No clear testcase.
+ No clear testcase. Ensure there is no additional or new gtk-window-
+ decorator crash.
  
  [REGRESSION POTENTIAL]
  
  Minimal, 10 lines added in the fix for cleaning the pixmaps that were
  destroyed.
