Comment:
I have the same error as kuraga, I report here the result of my
investigation.
== Problem ==
The list of torrents takes time to load at startup with the current
version of Deluge 2.0.3 from the offical ppa deluge-stable installed for
Ubuntu 1.04 Bionic.
The problem seems located in the GTK UI component of Deluge and it leads
to too many open files error. It seems to be a problem of passing a null
parameter to the cmp function in `deluge/ui/gtk3/common.py`.
I have around 60 torrents, seeded correctly with Deluge 1.3 or
Transmission.
== Reproduce error ==
After a successful fresh install of Deluge 2.0 and a first start in
standalone mode without any error, I add torrents in seed manually via
`menu -> File -> Add Torrent` everything seems right so far. Then I close
and restart Deluge. It starts with an empty list of torrent and it takes
several seconds to load them. It may sometimes crash at this point or just
run slowly and starts to use more and more CPU ressources.
To track the problem you can watch in your system log file (personally I
use `journalctl`) or just start Deluge in terminal and see the error.
This error is repeated houndreds of times

And finally the last line of error is:
{{{#!div style="font-size: 80%"

}}}
== Diagnostic ==
I have installed the package `deluge 2.0.3-2~201906121747~ubuntu18.04.1`
provided by the `ppa:deluge-team/stable` for Ubuntu 18.04 Bionic, Python
3.6 is used to run Deluge with `libtorrent: 1.1.5.0`
Prior to the installation of Deluge 2.0.3, I have purged all packages
related to Deluge 1.3 from the universe repository of Ubuntu: `deluge
deluge-common deluge-gtk` and moved my `~/.config/deluge`
I run the command `deluge -L=debug -l=deluge_debug
--profile=deluge_profile &!` to report information about the bug. The
following are extracts from `deluge_debug` that might help to track the
problem.
Around line 397 and repeated somtimes in the rest of log after:

}}}
Something weird happens, around line 516 everything seems fines:
{{{#!div style="font-size: 80%"
{{{#!console

}}}
}}}
in between all torrent seems to be loaded correctly and latter:
{{{#!div style="font-size: 80%"
{{{#!console

}}}
}}}
however it is a bit contradictory with the message received in standard
error output:
{{{#!div style="font-size: 80%"
{{{#!console

torrents.fastresume: [Errno 24] Too many open files:

}}}
}}}
In the end the log is full of:
{{{#!div style="font-size: 80%"
{{{#!console
