Bug#351452: gnome-panel: wnck-applet stuck in a loop after ssh-askpass.

[Fabien Ninoles]

Package: gnome-panel
Version: 2.12.3-1
Followup-For: Bug #351452


I have the exact same problem and it seems to also exist on gentoo
(http://bugs.gentoo.org/show_bug.cgi?id=121828).  I have my bt for
before, during and after the call to
ssh-askpass (X11 only - The problem doesn't exist with other ssh-askpass
alteranatives).  The first show a normal idle mode, but the two
others seems to be stuck in a mutex lock loop, or something similar:
here the interesting bits:

So, it seems that the problem is more related to libwnck (and also to
the way x11-ssh-askpass handles its dialog window).
