remove write
It seems that there is some problem with the functions
clear_outstanding_tvbs(), clear_outstanding_trees() and
clear_outstanding_pinfos(). These functions looks like the same, they use the
g_ptr_array_remove_index_fast() function to remove a pointer from the pointer
array called "outstanding_stuff".
This pointer is added to the "outstanding_stuff" pointer array by the
g_ptr_array_add() function. The pointer itself is created by the
lua_newuserdata() function. The lua_newuserdata() function is called from the
macros PUSH_TVB, PUSH_TVBRANGE, PUSH_TREEITEM, PUSH_COLUMN and PUSH_COLUMNS.
What is not clear for me is that why should we collect these pointers if Lua
will gc the userdata anyway?

After applying this patch the crash is not there anymore.
