[Bug 688700] Re: gvfsd-sftp several minutes consumes all available CPU resources , if try connect to unreachable SSH host.

2013-10-28 Thread Ville Ranki 
Looks like i just encountered this issue. I have a sftp host which was
unaccessible for some time (ssh connection just hangs). The host started
working but I was wondering why the computer felt slow. This is the
reason (output from top):

Looks like gfvsd-sftp does not handle the error condition properly and
is stuck in busy loop.

Backtrace of the situation (doesn't look very helpful):

I'm not sure if the issue can be easily reproduced but there seems to be
a bug.
