valgrind output (53.54 KB, text/plain) 2009-07-21 05:35 UTC, Greg	Details

Description Greg 2009-07-13 12:07:35 UTC

Steps to reproduce:
gnome-keyring-daemon crashes the first time I try to ssh to anywhere. In the terminal I get "Error reading response length from authentication socket."

What should happen is the box should pop-up to prompt me for the password to unlock the password protected ssh key.

Comment 1 Stef Walter 2009-07-19 19:58:40 UTC

I'd like to research and find this problem. Could you run gnome-keyring-daemon under valgrind (instead of gdb)? 

You'd run something like:

# valgrind /usr/bin/gnome-keyring-daemon --foreground

And then paste the environment info into another terminal, ssh, and post the valgrind output in this bug report.

Attached valgrind output as requested.  Thanks for looking at the bug.

Comment 3 Stef Walter 2009-07-21 13:45:16 UTC

I can confirm this problem has been fixed in gnome-keyring 2.26.3 and later:
