This still happens in Karmic with Seahorse 2.28.1.

[Bug 57433] Re: [Edgy] seahorse crashed at startup (segmentation fault)
I didn't send the patch upstream yet. I don't understand why the patch helps. But when I install 0.9.3-0ubuntu1 again seahorse segfaults. I also built seahorse several times locally (with and without optimisations) to find the problem but all segfaulted also. Only the builds containing the patch didn't segfault. -- [Edgy] seahorse crashed at startup (segmentation fault) https://launchpad.net/bugs/57433 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Ok, I'll debug it further tomorrow and if I don't find the reason I'll upload with your patch for now :) -- [Edgy] seahorse crashed at startup (segmentation fault) https://launchpad.net/bugs/57433 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Michael, could you try the patch at the upstream bugreport (comment #9) on a plain seahorse 0.9.3?
