Description Jakob Unterwurzacher 2009-04-29 12:10:29 UTC 
Steps to reproduce:
1) Go to some Windows share in nautilus
2) Start to copy some large file
3a) Pull the network plug, wait 10 Secs, replug it
 -OR-
3b) shut down the remote computer

=> gvfsd-smb hangs at 100% CPU
=> You can't disconnect the share
=> All smb access is broken
=> You have to kill gvfsd-smb to recover

Stack trace:
(gdb) backtrace full

+ Trace 214929

The program is running.  Quit anyway (and detach it)? (y or n) Detaching from program: /usr/lib/gvfs/gvfsd-smb, process 30621

Comment 1 Ross Lagerwall 2014-04-21 22:33:22 UTC 
The hang actually occurs in libsmbclient (the library the gvfs uses for smb access).

This appears to have been fixed in more recent versions of libsmbclient, and the copy fails with "Invalid argument" (admittedly not a great error message).
