Description of problem:
Crash happened during opening NFS directory containing pictures with gthumb 3.2.8. No files are being shown, instead a message"ghetting folder listing", infinitely. The NFS server is running fine. Chdir and looking at files is possible. Watching the pictures with gwenview as well. 

This machine is being used infrequently, the crash happened after an update from Kernel 3.12.7 and gthumb 3.2.5. 
Just before the update it did work fine. 

I did somehow expect these problems after the update because my primary machine has the very same issues running the same up-to-date fedora. It crashes every time I try to use gthumb to look at pictures on the nfs server. But since I use the proprietary nvidia graphics driver I did not report it. I cannot exactly say when these problems did occur for the first time, I guess a couple of weeks ago. 

I tried a new installation on that machine on a different partition and got the same problems (after updating, did not try setting nfs up before). 

However I own a third machine which does not show this behaviour. It runs the same fedora system as well. Browsing the nfs directories with gthumb is possible. That machine is a notebook with an AMD E450 CPU, while my main System uses a AMD Phenom II. While on the other machines I use KDE, on the notebook XFCE is being used. But I also tried using XFCE on the primary machine, It did not improve the behaviour. 

Personally I do not have a clue what the reason could be. Since the laptop was working fine, I believed in a hardware error, but since this machine has the same issues, but only after the update, I am lost completely. Maybe there is a bug in some hardware-dependant functions.


Thanks for looking into it.

Cheers,
Jo
