thunar sometimes hang when going to parent directory

[Scaramanga]

When I go back to a parent dir with backspace thunar will sometimes lock up.
The directories where it usually happens have a lot of files and folders. About 180-600.

I have been able to reproduce the lockup on demand, sort of, by holding arrow down for a few seconds. Then, while still holding arrow down, I press backspace to go back to the parent directory. The hang usually occurs within 3 attempts.

I'm using Xubuntu 14.04.1 64bit.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/Xfce. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

Did you forward this issue upstream?

I have not. That should be automated. Having to register and re-enter the issue details on yet another bug tracker is more of a hassle than I'm willing to put up with. I have switched to PCmanFM which is much more stable and also quicker at loading folders with many files. The only downside is that it doesn't have Thunars nice mass-rename feature.
