Hi Thaddaeus, I'm experiencing this issue with version 1.6.10 of Thunar as well, on Xubuntu 15.10 (Wily Werewolf). I cut a file from one tab, then pasted in on another tab of Thunar, and the file manager suddenly vanished. I got
*** Error in `Thunar': double free or corruption (out): 0x00007f72f00196c0 *** in my ~/.xsession-errors file. And this is apt-cache policy thunar: thunar: Installed: 1.6.10-1 Candidate: 1.6.10-1 Version table: *** 1.6.10-1 0 500 http://us.archive.ubuntu.com/ubuntu/ wily/universe amd64 Packages 100 /var/lib/dpkg/status -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1425643 Title: thunar assert failure: *** Error in `/usr/bin/Thunar': double free or corruption (fasttop): 0x00007f9178009e70 *** To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunar/+bug/1425643/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
