New crash information added by DrKonqi

dolphin (2.0) on KDE Platform 4.8.5 (4.8.5) using Qt 4.8.1

- What I was doing when the application crashed:
It has happen again. The only difference is that this time I had already been filtering before, and started to filter from a previous result. In fact, I filtered 2 or 3 times before the crash.

Comment 4 Frank Reininghaus 2012-11-14 16:28:31 UTC

Unfortunately, looking at the code doesn't tell me yet how such a crash can happen :-( If anyone finds a way to reproduce this, please let us know.

Comment 5 Frank Reininghaus 2013-01-08 18:28:35 UTC

From bug 312881:

- What I was doing when the application crashed: I had a subfolder expanded and deleted a file in there. Then from another terminal I created a file with the same name in the root folder I was viewing and I went back to dolphin starting to type the file name into the filter bar when it crashed...

Just for the record, there is a reproducible crash with this backtrace (bug 311947), which is about making an expanded folder hidden by adding a dot at the beginning of its name. The problem is, like here, that there are child items without parent in the view.
