            Bug ID: 16357
           Summary: Opening any file via FTP Causes Segfault (Core Dumped)
    Classification: Xfce Core
           Product: Thunar
           Version: 1.8.11
          Hardware: PC (x86_64)
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Medium
         Component: General
          Assignee: xfce-bugs at xfce.org
          Reporter: admin at scorpex.org
  Target Milestone: 1.8.12

I have a VERY strange bug that is only happening when using Thunar with Linux
Kernels >= 5.4, everything 5.3 and below is working fine. I recommend using
Arch Linux since it is rolling release and will use the latest Kernel. This
issue can be easily replicated by opening an FTP site via thunar and open a
file on the FTP site to edit (a text file for example). The file will never
open, instead it will generate a core dump (Program terminated with signal
SIGBUS, Bus error).

I am not 100% certain if this is a dbus, gvfs, etc issue instead, but I wanted
to report it here since it is causing remote FTP editing of files to break with
Thunar. I would be happy to provide any further information that could be
helpful.


Here is the backtrace of the coredump.

[Thread debugging using libthread_db enabled]
=> Using host libthread_db library "/usr/lib/libthread_db.so.1".
=> Core was generated by `mousepad
/run/user/1000/gvfs/ftp:host=ftp.host.com/somefile.txt'.
=> Program terminated with signal SIGBUS, Bus error.
