Hello, let me clarify your doubts, so it will be easier to debug. :-) > I'm sorry to hear that, but I don't think I can reproduce that (also it's > unclear what “shredding” exactly means here). It means standard secure deletion by using "shred" from the GNU Coreutils. GNU shred: https://www.gnu.org/software/coreutils/manual/html_node/shred-invocation.html Command: $ shred -zu smallFileOnUSBkey.txt > Also it's quite likely that you > actually removed the USB key while the thunar process was still having > open fd > on the usb key, which is definitely the wrong thing to do. The file was deleted from the key but did not disappear from Thunar, because the GUI was totally frozen. After a while the WM reported that Thunar was frozen and asked me to terminate it. After restarting Thunar, I managed to eject the USB key and the chain of crashes and slowness began.
To further help you to reproduce the problem, this is the USB key entry from "/etc/mtab": /dev/sdb1 /media/lorenzo/36FD-4552 vfat rw,nosuid,nodev,relatime,uid=1000,gid=1000,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,showexec,utf8,flush,errors=remount-ro 0 0 Regards, Lorenzo On Wed, 20 Dec 2017 14:46:40 +0100 Yves-Alexis Perez <cor...@debian.org> wrote: > control: severity -1 important > control: tag -1 unreproducible moreinfo > > On Tue, 2017-12-19 at 20:58 +0100, Lorenzo Ancora wrote: > > Dear Maintainer, > > shredding a file in a mounted USB key causes `Thunar 1.6.11 (Xfce 4.12)` to > > block permanently. > > The window with the key won't close and Thunar must be killed manually; it can > > be restarted (must wait 2 minutes on a Intel Core i5) but is very slow and you > > can just eject the USB device.
