Application that crashed: dolphin
Version of the application: 1.2.80
KDE Version: 4.2.87 (KDE 4.2.87 (KDE 4.3 >= 20090519))
Qt Version: 4.5.1
Operating System: Linux 2.6.29-ARCH i686
Distribution: "(none)"

What I was doing when the application crashed:
Just tried to reproduce bug 181536 and I got this. 
As it is a different backtrace I'm reporting this issue in a new report

I did:
- Open Dolphin
- Split window (f3)
- Show Home on the left part and Root on the right one
- Right click on the Left part and select Properties...
- I clicked cancel and nothing happened
- Right click on the Left part and select Properties..., again
- Click OK

Dolphin crashed. 
Interestingly, Kate also crashed in the same moment with the same backtrace. 
(Note that before rightclicking on the left part, I tried on the Right one (showing Root) without crashing)

 -- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
