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:

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

Hardware info:

    * 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! :-)

Hello again, maintainers,

I was finally able to get Thunar built with debug symbols and started it under gdb. In Thunar, I navigated to a folder in my home directory, double-clicked a sound file to play it, then minimized Thunar. I then performed the following commands repeatedly and Thunar crashed while sitting unused/idle:

    sudo pkg remove -y smplayer && \
    sudo pkg autoremove -y && \
    sudo pkg clean -ay && \
    sudo pkg install -y smplayer && \
    sudo ldconfig

The gdb output and backtrace are below:
