           Summary: Dolphin Freeze while opening nfs mount with several

SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.

STEPS TO REPRODUCE
1. mount nfs point with several folders without having even read write (nfs4
only??)
2. try opening application-starter or any other program pinned to the taskbar
3. await several notifications, that it was not able to open the mountpoint
4. then it works again

OBSERVED RESULT
- fan speed increases (due to higher CPU load?)
- Dolphin freezes for a few seconds
- Taskbar, Application Starter, Widgets etc. freeze until...
- ...several notifications pop-up, that the filesystem does not respond.

EXPECTED RESULT
- no freeze while opening mountpoint with several restricted access folders
- immediate opening of the mountpoint
(- maybe even hide the folders, the user does not have access to?)
