kde save dialogs and nfs shares

[Tim Folger <tf@timfolger.net>]

I'm running an up-to-date version of jessie with kde 4.13.3. After a routine 
upgrade last night I started having problems with kde's save dialogs in google 
chrome and also in opera. When I tried to save a page in either browser the 
save dialog box remained grayed out and never loaded. A couple of times the 
entire desktop locked up and i was forced to do a hard shutdown. The save 
dialogs worked fine in dolphin, konqueror, calligra, etc. 

After some googling I found that unreachable network shares might be causing 
the problem, so I commented out one unused nfs share in /etc/fstab and now the 
save dialogs work as expected in chrome and opera. Is there any other solution 
to this problem other than the one I'm using, i.e. commenting out inactive 
network shares in /etc/fstab?

Thanks for any thoughts.
