OS crash on Mac using any recent FileZilla build

[stevepodradchik]

For > 1 year, loading a directory list causes a crash in Mac OS. Installed multiple OS updates, multiple FileZilla updates, etc. Crash generally happens on directory listing but sometimes takes opening a few directories before the crash happens. I would also note that NO OTHER APP causes anything like this and I am a software developer so please do not blame the OS -- just workaround any OS issue if there is one. Very, very easy to repro. Let me know if you need more info but I think the Mac version, Mac OS version, and FileZilla version are included here. The only 3rd party kexts is the Forinet security/VPN client and .. no .. removing it does NOT make any difference (tried that).

Screenshot are available but apparently are too large to upload. Happy to email directly or maybe time to increase the file size limit beyond about 250K?

System crashes cannot be caused by ordinary programs. There must be an underlying problem with your system, be it third-party kernel extensions, the operating system itself or your hardware.

Make sure to remove all third-party kernel extensions[1]. If the problem persists you need to contact Apple for assistance.

[1] Case in point: Third-party kernel extensions are so problematic in general, that Apple will make it much harder to use kernel extensions in the next version of OS X.
