Hi,

Tested on 3.1beta1. It does not look like later commits fix this bug. To reproduce (always here):

Selected a torrent with folders, go to the InfoWidget -> Files, right click on the folder and ktorrent crashes. The backtrace below:

Code: Select all

Application: KTorrent (ktorrent), signal SIGSEGV

I can reproduce it, so it should not take long to fix.

It is fixed
