Public bug reported:
I can reliably get gnome-shell to dead-lock while using gmusicbrowser
with all the music on an sshfs mounted filesystem.
Steps to reproduce.
Computer A is the desktop, B is the remote server that hosts the filesystem.
1. On A, mount the remote filesystem on B with sshfs with the option '-o
reconnect'. This will trigger ssh-askpass later.
2. On A, start gmusicbrowser and set the library to the mounted sshfs
filesystem.
3. Play a song and pause it.
4. Remove focus from gmusicbrowser, for instance but putting it on another
workspace.
5. Reboot B.
6. Wait for B to come up.
7. On A, switch to the workspace with gmusicbrowser and the first click you do,
click the settings gear to get the floating window.
8. Enjoy your dead-lock
When gmusicbrowser gets focus it first opens a floating menu, but also
it triggers a reconnect to the sshfs filesystem since it has a mp3 file
open, and this starts ssh-askpass, which opens a dialog to get your
password, but it cannot get complete focus because of the floating meny
and now displays an alert "cannot get complete focus, maybe someone is
eavesdropping", which cannot be clicked because it can't get focused.
Gnome-shell is completely deadlocked, mouse still moves, but nothing can get
focus, hot corners does nothing, typing does nothing. Killing gmusicbrowser
does nothing, killing gnome-shell restarts it into the same dead-locked state.
The kernel complains that gmusicbrowser is hung for over 120s. Xkill can't grab
the mouse is says.
You can get out the dead-lock by using 'pkill ssh-askpass' for another
vt, but that took me a long time to figure out.
