pcmanfm crashed with SIGABRT in g_assertion_message()

How to reproduce: Open PCManFM to any directory, modify any file in that directory, then save from your editor, and PCManFM will crash. This only seems to happen some of the time.

Xubuntu 16.04, PCManFM 1.2.4-1

System info:

Description: Ubuntu 16.04 LTS
Release: 16.04

pcmanfm:
  Installed: 1.2.4-1

This may be useful - I got a more descriptive error:

GLib-GIO:ERROR:/build/glib2.0-7IO_Yw/glib2.0-2.48.1/./gio/glocalfilemonitor.c:433:g_file_monitor_source_handle_event: code should not be reached

in the output when running PCManFM from the Terminal and reproducing this bug. Full output:

aaronfranke@aaron-xub16desk:~$ pcmanfm
** Message: x-terminal-emulator has very limited support, consider choose another terminal

** (pcmanfm:26132): WARNING **: XDG_TEMPLATES_DIR is set to invalid path, ignoring it

Aborted (core dumped)

So, I think that this error may have something to do with GLib/GTK
