How long was that click? I can seem to reproduce here.

Just to be clear, you are clicking on a RSS news article in the top-right list?

Unfortunately the backtrace is not helpful here. If you can reproduce easily, it might be useful to get a backtrace with gdb:

# apt-get install gdb
$ gdb qbittorrent
> run
... Make it crash ...
> thread apply all bt 25
.. Will be a backtrace ...

Damn, I really cannot seem to fix it properly. The thing is I haven't been able the reproduce the issue in a long time (Since my first fix actually).

Okay , if you want to reproduce , follow the following steps:

1 : Subscribe to ezRSS or any other popular feed.

2 : Go to (Unread), and make sure there are many unread articles.

3 : Left click on the last article and drag UP.

4 : CRASH
