SUMMARY

Hello, Whenever an application trys to open a directory and if dolphin's
instance is already in that directory
dophin crashes with added backtrace

I have hit this bug with an application called simplescreenrecorder but i
believe same bug can be observed
with other programs which does same thing ( trys open a directory )

STEPS TO REPRODUCE
1. click open directory ( from any app )
2. if dolphin doesnt have any instance open and not showing that directory
everthing is ok
3. click again ( or simply get same directory which external app tries to open
)
4. crash
