using xfce4 desktop 4.8.3-2

I start LibreCAD, and nearly anything I do that relates to the file system causes a complete crash of X, bringing me back to the desktop login.

Any of the following causes an immediate crash of the desktop (not just the program)

"file -> open"
"file -> save"
"edit -> application preferences -> anything"  (note that the application preferences window successfully pops up, but as soon as I try to click on anything in the window, my desktop crashes [except for cancel].)

One thing I will mention.  I use several computers with an NFS mounted home dir.  Because of this, I set XDG_CONFIG_HOME to keep a unique desktop for each computer.  I don't know why this would be an issue unless LibreCAD does not follow the standard X configuration API.  I'll run a test by linking my XDG_CONFIG_HOME to ~/.config and see what happens.

OK, that didn't help at all.

I also tried logging in as another user, and as root - same results

I also tried using a different window manager or two, with the same results.

I'll try on one of my other computers tomorrow...
