QT Creator crashes when accessing file system in side panel

[LesF]

Hi, I'm kind of new to this IDE and may have missed something in setup, but I cannot access the file system from the side bar. I use the side bar drop-down to select File System and it lists the contents of my home directory. If I click on a file or folder in that listing, it crashes, with...

$ qtcreator
Got bus address: "unix:abstract=/tmp/dbus-2zEJKwFeyo,guid=d28ec5d22e31b9bb7f6e537e000001bd"
Connected to accessibility bus at: "unix:abstract=/tmp/dbus-2zEJKwFeyo,guid=d28ec5d22e31b9bb7f6e537e000001bd"

Is this something I have overlooked? Reluctant to log a bug if this is something silly on my side.

Using:
Ubuntu 12.04 64bit, with KDE installed from software centre: kde-standard 5:71~pre15ubuntu12.4
QT Creator from the ubuntu software centre, it shows version 2.4.1 based on QT 4.8.0 (64 bit).

Try to install 2.5 first, it is in software center. If software center doesn't allow to update version directly, uninstall qtcreator, select version 2.5 and than install it again.

Thanks I hadn't noticed that alternative version hidden in there. Have changed to 2.5 but still get the same crash. Tried creating a gui project, and when I open the File System panel in side bar it then lists the contents of the current project. Trying to access any of the files in that panel still crashes it tho.
Its not really a big issue as I don't need to use that File System panel, was just curious why it has te problem tho.

Now with version:
Qt Creator 2.5.0
Based on Qt 4.8.1 (64 bit)
Built on Jun 28 2012 at 14:40:34

and getting:
$ qtcreator

Looks like rare bug, and uninstalling qt-at-spi should help (it is just an accessibility plugin).

I've never seen this happen before. This looks like a crash in the accessibility part of Qt itself.

Where did you get Qt Creator? There were reports about trouble with the ubuntu-provided binaries before, could you try to use the Qt Creator stand-alone binaries from the download section?
