Description Christoph Lange 2008-11-10 22:58:08 UTC

Version:           1.3.3 (using 4.1.3 (KDE 4.1.3), Gentoo)
Compiler:          x86_64-pc-linux-gnu-gcc
OS:                Linux (x86_64) release 2.6.24-tuxonice-r4

How to reproduce:

1. drag a folder towards the end of the folder list/tree
1. while dragging, wait for the mouse cursor to become a "plus" instead of a "forbidden" sign
1. drop, i.e. release the mouse button, at a place at the end of the list where the cursor picture indicates that you may drop
1. Akregator crashes

Hi!
I've just reproduced the crash using current trunk (r882292)


Here is the backtrace:

*** This bug has been marked as a duplicate of bug 164265 ***

*** Bug 185484 has been marked as a duplicate of this bug. ***

Comment 4 Dario Andres 2009-02-24 23:39:35 UTC

is this really a duplicate of bug 164265 (I don't see the relation between the backtraces and situation)

BTW, Bug 185484 is happening at KDE4.2

Should this be reopened ?

Comment 6 Stefan Dotterweich 2009-02-24 23:53:35 UTC

i don't think #164265 is related to this, as you say it's a completely different situation and this bug still exists.

should be reopened
