Loading a blend file or reloading the same file after working on some a blend file crashes on wm_handler_fileselect_call(..) in wm_event_system.c on line 1295 in the check for "if(wm->op_undo_depth == 0)".

It seems that the wm can get changed by the operator somehow, so the wm pointer can be corrupt after the operator exec. In other cases around the line a check for (CTX_wm_manager(C) == wm) is used before accessing anything through the old wm pointer, so I guess this is already a known issue, but just a missing check on line 1295?

Mostly this happens on the second load, but other times a couple of loads are needed. This happens with either loading through a hotkey or from the menu entry.
