The following sequence leads to crash:

0. Configure Dolphin to use per-directory view settings (in particular Items/Details view mode)

1. Open some directory with list view mode

If one go to the same directory via "Places" link, there is no crash

The crash can be reproduced every time.

Comment 1 Eugene Shalygin 2010-10-15 11:25:42 UTC 
"If one go to the same directory via "Places" link, there is no crash" - even if one clicks the link when Dolphin is in directory from item #1
