Stack Trace from gdb

I had version 3.16 I believe (maybe old installation from git on top of Fedora package) and now I've installed 3.17.3git41 and the issue still happen.

It runs for a while and it freezes for no reason consuming 100% of one of my CPU threads (I have 8 - 4 cores + hyper thread).

To fix I need to kill claws-mail and run it again. Sometimes it don't consume 100% CPU, I can click on message (in message list) but the message details view is not changed, and just after I click the message it consume 100% CPU (1 thread) - this is the case I'm seeing now. I have message in status bar that he try to fetch message from one of my mailboxes, I'm not sure if it was always there when It freezes.

I'm attaching the gdb stack trace (out of CTRL+C + `thread apply all bt`).

this is the last message I've got before I hit CTRL+C to get stack Trace:

This is probably related to http://www.thewildbeast.co.uk/claws-mail/bugzilla/show_bug.cgi?id=2922
Comment 3 Paul 2019-03-01 16:16:31 UTC
There's a problem with libnotify on fedora. If you are using the Notification plugin, try unloading it and see if that helps.
Comment 4 Paul 2019-03-01 16:24:45 UTC
I loaded the Notification plugin on fedora, using the sysTrayicon module, and I get the 'freezes' on receving mail, and the 100% CPU spike on 1 cpu. `claws-mail --debug` shows

(claws-mail:5999): libnotify-WARNING **: 16:18:59.090: Failed to connect to proxy

several times during this.
Comment 5 Jakub Jankiewicz 2019-03-01 17:47:30 UTC
So it's bug in Libnotify, I also found report for other app with same error/warning and freezing
https://github.com/meetfranz/franz/issues/592

and reported it to Fedora:

https://bugzilla.redhat.com/show_bug.cgi?id=1684638
Comment 6 Jakub Jankiewicz 2019-03-05 11:02:47 UTC
I have question, should it also freeze (same libnotify issue) when I'll use the plugin but disable notifications in options to have tray tray icon?

Because it just freezed after few days without issues.
Comment 7 Mike 2019-03-29 02:33:39 UTC
In Windows, I find frequent freezing and similar issues as described above-- freezing just when mail is received, and when switching messages.
