Bug 262771

+++ This bug was initially created as a clone of Bug #262768 +++

Version:           unspecified (using KDE 4.4.4) 
OS:                Linux

When I try to copy many files from one of my logical disks (summary size of files is 3.1 GB; NTFS partition) to another one (NTFS too) Dolphin copies only ~2.5 GB. Some files are NOT copied. This can lead to data loss. When doing the same with Krusader I experience the similar problem but another files are not copied (it copies ~2.6 GB of 3.1 GB). Files that are not copied are different in Dolphin and Krusader but they always are the same in each of these programs respectively. I experience this problem when trying to copy many files from another logical disk too. The path to most of them is less them 255 characters and often does not contain spaces and non-latin symbols, nothing exotic or non-valid in paths.

Midnight Commander and cp copy everything fine.

Reproducible: Always

Steps to Reproduce:
Just copy many files from one disk to another one. Then check the size of the destination folder. I have NTFS on both partitions. I did not try another file systems yet.

Actual Results:  
The destination folder size is less the the source folder size. Tools like Synchronize in Krusader will show the difference. Some files are missing in destination folder after copy operation.

Expected Results:  
Should copy everything.

Midnight Commander and cp copy everything fine.
