Bug 337425

Application: kate (3.13.2)
KDE Platform Version: 4.13.2
Qt Version: 4.8.6
Operating System: Linux 3.13.0-32-generic x86_64
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

1. Mounting a slow network mount with CIFS in /mnt
2. Start Kate
3. Go to File -> Open  File and trying to navigate the filesystem

- Unusual behavior I noticed:

All is slow/stalling, takes about 30-90seconds, regardless whether it's local fs (e.g. change from ~ to / or change from ~ to ~/Desktop)

Killed then Kate while it's stalling with   kill -ABRT PID

I can repeat this in Konqueror and also in Okular. However in Dolphin it all works fine... no stalling at all, except when I access that slow cifs mount, then it's slow there... all others are just fine.
