I can confirm exactly the same behaviour: Seahorse becomes unresponsive with 100 % CPU upon trying to edit the key properties of GPG keys DAFFB000 / B3B2A12C.
System details: Seahorse 3.2.2-0ubuntu2.1 Ubuntu 12.04.3 amd64 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to seahorse in Ubuntu. https://bugs.launchpad.net/bugs/1055175 Title: seahorse stops responding after importing a key with al lot signatures. Status in “seahorse” package in Ubuntu: Confirmed Bug description: I imported two key with a lots of signatures in seahorse. Now seahores tries syncing these key for hours and isn’t' responding any more (using 1 core 100%). Killing the process an all gpg instaces works but only for so long before I reopen seahorse. Keys I imported: - DAFFB000 - B3B2A12C The problem occurs all the time I want to set an option in the properties of on of these keys (like sign them oder set a trust). seahorse immediately freezes.But i think the problem is triggered on other occasions as well like syncing the key etc. Ubuntu Version Description: Ubuntu 12.04.1 LTS Release: 12.04 Seahorse Version: 3.2.2-0ubuntu2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/seahorse/+bug/1055175/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
