Thunar SIGSEGV's immediately on start when last directory no longer exists
When I use thunar at work, the directory shown in thunar when I close thunar is usually deep within a network drive.
When I then try to open thunar at home, this network drive does not exist, and thunar immediately segfaults.
The workaround is to edit .config/xfce4/xfconf/xfce-perchannel-xml/thunar.xml, set the property "last-tabs-left" to some existing directory, and restart the whole Xfce session (logout+login). After that, thunar starts without problems.
