[Konversation-devel] [konversation] [Bug 314082] Crash while using mouse scroll wheel

--- Comment #6 from Hebert <hebert.soares at gmail.com> ---
Updated KDE to 4.10.2
Qt is alredy 4.8.4
Using Fedora 18
Update konversation from git to 1.5-master #4300.
Still able to reproduce it.
One of the things I should mention is that I reproduce it using the mouse wheel
by doing horizontal scrolling. If I scroll the list of channels horizontally
all the way to the right, it will crash when it is scrolled back to the left.

New backtrace:
