FreeBSD Port: Thunar-1.6.7_1

[Will Brokenbourgh]

Greetings maintainers!  Thank you for all of your hard work! :-)

I am using the binary package of Thunar on FreeBSD 10.1 amd64.  It has 
now crashed several times since my clean system install yesterday, and 
almost every crash the error message is:

> GLib (gthread-posix.c): Unexpected error from C library during 
> 'pthread_mutex_lock': Invalid argument. Aborting.

The crashes seem to happen during moderate disk usage, but there is no 
definite pattern and trying to intentionally crash it repeatedly is 
difficult.

First notable crash was when I had selected several files with Thunar in 
~/.local/share/applications using Ctrl+left click, then right-clicked 
one of the selected items and chose 'Delete'.  In the middle of the 
delete operation, Thunar crashed with the above message.

Another notable crash: Thunar was opened to a folder in my home folder, 
sitting unused and idle, minimized/iconified.  I opened xterm (from 
lxpanel, NOT Thunar), then performed 'sudo pkg install smplayer'.  
Thunar crashed with the above message at the latter part of the package 
installation.  I have noticed a few times in the past that some apps 
will crash while sitting idle when I am performing operations with pkg 
in xterm.

I have also tried building Thunar from the ports tree with WITH_DEBUG, 
but when I opened the core dump with gdb, the backtrace only provided 
useless numeric addresses, no function names or files.

dmesg at time of crash:
> pid 941 (thunar), uid 1001: exited on signal 6 (core dumped)

Other apps running:
     openbox, lxpanel, thunderbird, firefox and xterm

Hardware info:
     * AMD 6-core processor (dmesg: "AMD FX(tm)-6300 Six-Core Processor 
(3511.78-MHz K8-class CPU)")
     * Asus M5A97 LE R2.0 motherboard
     * Radeon HD 5450 video card
     * 8 GB RAM
     * 500 GB 7,200 RPM Samsung hdd (dmesg: "SAMSUNG HD502HJ 1AJ10001")

On Ubuntu and other Linux distros, Thunar is very stable and hasn't 
crashed like this on the same hardware.

Please let me know if I need to provide additional information.

Thank you and God bless! :-)
