Crashes after closing the window

[azarovalex]

There are crashes I sometimes catch after closing the MachOExplorer window. The problem is similar to https://github.com/DeVaukz/MachO-Explorer/issues/10, but the crash log looks different to me.

Here is an example stack trace:

This crash may be difficult for me to investigate from crash reports only. If you could run Mach-O Explorer with the Zombies Instrument and capture a trace while the crash happens, that would be helpful.
