Bug#825142: gvfs-backends: gvfsd-smb-browse goes to 100% CPU until killed

[Christoph Anton Mitterer]

Package: gvfs-backends
Version: 1.28.2-1
Severity: important


Hi.

It happens every once in a while, that a gvfsd-smb-browse goes up to
100% CPU and stays at that until forever (or I'd kill it).

In all those cases I haven't really done anything related to smb, nor
have I had any smb server at all in the local network.

The only thing I found last time in the logs was the following from
journalctl:
May 24 03:44:59 heisenberg org.gtk.vfs.Daemon[5225]: ** (gvfsd:5297): WARNING **: dbus_mount_reply: Error from org.gtk.vfs.Mountable.mount(): Message recipient disconnected from message bus without replying

Any ideas (including on how to track that down better)?

Thanks,
Chris
