Sentry Crash Report:

Description Paul Mus 2013-09-10 07:21:24 UTC 
The length of the of softlink target names is too short. 

If you create a set of softlinks using the script below, and then successively open the subdirs then you will see that the softlinks become dysfunctional if the target name length exceeds 256 bytes. In Dolphin, everything works fine beyond this length.


Reproducible: Always

Steps to Reproduce:
1. Create a directory named "temp" in your home directory
2. Execute the script shown below
3. Follow the "directoryB-" folders down the folder tree and click on the softlinks to "directoryA-"
Actual Results:  
At the beginning of the folder tree you can open "directoryA-" folders using the corresponding softlink. But at a certain level down the tree (depending on the length of your $HOME), the softlink stops being functional. If you open Properties, you will see that the target name has become incomplete beyond 256 bytes.

Expected Results:  
The softlinks are usable for target names up to the maximum length of filepaths in Linux.

This is the script I used to create the directories and softlinks:
