[Pkg-xfce-devel] Bug#714736: thunar: GUI freeze while moving to trash a file from a NFS4+Kerberos mount

[Sylvain Leroux]

Package: thunar
Version: 1.2.3-4+b1
Severity: important

Dear Maintainer,

Users experience a "GUI freeze" when they move to trash a file with
Thunar on a machine where /home is remotely mounted using
NFS4 + Kerberos authentication.

For something like 30 seconds the GUI is not responsive (can't launch
other apps, can "move windows", but there is no window redraw). After
that finally the "move-to-trash" succeed.

It seems to only appears on user "/home" directory. This is the only NFS
mount on the system. Here is the corresponding /etc/fstab entry:

-------8<----------------------------------------
# /etc/fstab

real.chicoree.fr:/homes /home nfs4 rw,sec=krb5 0 0

Client machines are running stable Debian Wheezy. For now, there is no
workaround (beyond "just wait" -- or not using NFS4+Kerberos, which is
unacceptable in our case). This has an important impact on usability of
the system for the end user since the bug is regularly "in the way"
during day to day activities.
