New crash information added by DrKonqi

konqueror (4.4.80 (KDE 4.4.80 (KDE 4.5 Beta1))) on KDE Platform 4.4.80 (KDE 4.4.80 (KDE 4.5 Beta1)) using Qt 4.7.0

Still reproducable with on 4.5 Beta 1 (4.4.80)... seems to be within the places panel as konqueror is taken down aswell if that is opened while removing an USB volume.

Comment 6 Kevin Ottens 2010-05-29 13:24:04 UTC 
Tried to reproduce it today without success (r1131691). Could someone try again with this revision?

If you manage to reproduce it, we'll very likely need a more detailed description on how to reproduce it (in case some steps are missing or could be ambiguous).
Comment 7 Mikko C. 2010-05-29 13:28:01 UTC 
Still valid here, KDE svn compiled on Fri May 28 18:45:01 2010
To reproduce:
- plug in an usb stick
- mount it through the devices plasmoid applet
- (Dolphin should open automatically now)
- unplug the stick without un-mounting it 
- crash.
Comment 8 Kevin Ottens 2010-05-29 16:16:01 UTC 
Still can't reproduce... Someone else will have to pick this one I'm afraid.

New crash information added by DrKonqi

dolphin (1.4.9) on KDE Platform 4.4.81 (KDE 4.4.81 (KDE 4.5 >= 20100527)) using Qt 4.6.2

- What I was doing when the application crashed:

Here is more data, hopefully of some use:

- Dolphin crashes regardless of how the USB stick was mounted -- I tried via Notifier plasmoid and directly in Dolphin

- It crashes regardless of whether you dismount the stick or not before unplugging it

- If you open a folder that is *not* on the USB stick (eg, Home folder) and then pull the stick (with or without unmounting it), the Dolphin does *not* crash

Who's your daddy now? ;) Just kidding. :P Thanks guys, you are the bombs! I love KDE 4 :)

dolphin (1.4.9) on KDE Platform 4.4.85 (KDE 4.4.85 (KDE 4.5 Beta2)) "release 3" using Qt 4.6.2

- What I was doing when the application crashed:

I browsed to my USB stick in dolphin. I then unplugged my stick (without unmonuting it) and dolphin crashed.

Hi Kevin, big thx for squashishing this one! As it was a (un)pretty nasty bug and did survive for a relatively long time, this one might be especially interesting for experienced and unexperienced KDE developers alike. It would be great if you could elaborate a bit on why this one was so hard to track down, and how you exactly did it - merci ;)
