Hello,

I have encountered crashes using ktorrent since a few days. I'm using Ubuntu 7.10 Gutsy Gibbon, KDE 3.5.8 and ktorrent 2.2.1. I configured ktorrent to have 2 tabs, one for downloads and the other for uploads.

I discovered the crash when I tried to change the active tab, but I can reproduce it when I click on a torrent to select it. And I can reproduce it at any time

I tried to unload some widgets just in case, and discovered that when I try to unload Info Widget it crashes too.

Here is the error when I select a file:

Code: Select all

And here is the one when I unload Info Widget. It's lighter, and maybe useless, but here it is:

Hope it will help. Today if I want to check the progression of a download, I have to click on the vertical tab “Groups”, select “All torrents” and check it in the list. It could be better

As I'm here I'd like to congratulate you for the good work

[edit] I just updated to version 2.2.4 which seems to solve the problem. That was quick !
