SC 2.2.0 announced to be released on Monday May 8th. Release candidate available at http://claws.sylpheed.org/cvs.php.
So, reopen once there's some release at least...
Sorry... There were times RC were in portage too....
It's out: http://sourceforge.net/project/showfiles.php?group_id=25528
Yes, it's out and it builds and works fine. However, there is a little catch. Something in the 2.1.1 ebuild was broken. Claws would open, mail would be received, and then it would hang with the receive dialogue window open. CPU usage would max out and memory use would slowly increase until it was maxed out too. First, I thought it was 2.1.1, so I waited for 2.2.0 to upgrade from 2.0.0. I renamed the 2.1.1 ebuild and found the same problem. So I used the 2.0.0 ebuild, added the startup-notification stuff, and voila! It works fine.
Report it to developers ;) http://www.thewildbeast.co.uk/sylpheed-claws/bugzilla/
in CVS
The problem did, in fact, persist. It took me a while to pinpoint the problem, and I sent a report to the mailing list this morning along with links to plenty of debugging info. Amazingly, Colin Leroy (the main developer), contacted me directly less than an hour later. He wanted to see my matcherrc file, which I provided, and within another 30 minutes or so he sent me a patch to test. It turns out that he had rewritten some of the filter stuff, which broke some of my filter rules that had multiple actions. Anyway, the patch, applied to 2.3.0-rc3, fixed it.
