Bug Description

Binary package hint: gvfs

ubuntu 10.04 alpha fully updated.Aditionally tested in testdrive with daily iso, same results.
Version gvfs-1.5.5-0ubuntu1

If you try to connect to a sftp / ftp share via a password the gvfsd-(sftp/ftp) process hangs without results at 90-100%.
This only happens if you have been connected to the share before and the password is stored in the gnome-keyring. (View with seahorse).

Steps to reproduce:
1) Connect to a server (you haven't connected before) and select "forget password immediatly". The share will be mounted successfully.
Disconnect from the server.
2) Connect to a server and select "store password forever". The share won't be mounted and gvfsd-xx will eat your cpu.
As long as the password is stored you won't be able to connect. Delete the password (seahorse) and you will be able to do 1).

Hello Sebastien,
great you care. I have already been pointed to the debugging steps, but there is a problem.
The process gvfsd-sftp is called independently and talked via dbus. It's called like "gvfsd-sftp --spawner :1.7 /org/gtk/gvfs/exec_spaw/5". I tried to debug the gvfsd-sftp but this doesn't bring any results, as I cannot debug the dbus mechanism.
If you have further ideas, I will try to provide more information. The attachment is a try, I don't know if this helps anything.

you can attach the process using "gdb --pid <pidnumber>" and get the backtrace there

Thank you for the hint. Here is the trace.
I hope this will help to fix the problem. It is still reproducable with the updates from today.

could you install libdbus-1-3-dbgsym and libgnome-keyring0 too and get a debug stacktrace?

hello sebastien, here is a more detailed backtrace with more debug symbols.
Do you think we will have this fixed till lucid final?

the new stacktrace is good, not sure about lucid but that's the goal and it will be fixed in a stable update in any case if not before
