Compiler: GCC/G++ 4.4.1
Installed from: Compiled sources
When using Dolphin or Konqueror 4.3.80 in detailed view mode, selecting multiple files or folders with Shift+Arrows_keys won't work properly. It only highlights the last 2 selected items, deselecting the previously selected files or folder.
Also, it seems to only affect files/folder which are less than 48 characters long. As soon as a file/folder with a 48+ characters name is included, selection starts working as it should.
Thanks for the bug report! This has been fixed recently.
