Public bug reported:
Binary package hint: rdesktop
I have a few SSHFS FUSE mounts in /media (along with CIFS and NFS
mounts)
If the SSHFS connection has dropped then I can reconnect by trying to
access the dir e.g. ls /media/sshmount, this will reconnect in the
background and present the files after a few seconds.
When I am in rdesktop and try to copy files using the -rdisk switch to
share a local dir remotely (I use -rdisk:ubuntu=/home/darrenm) then the
copy will lock up the whole X session unless I xkill rdesktop, which
doesn't actually kill the process, the only way to get rid of it is to
reboot.
If I strace rdesktop I can see it trying to stat every mount and when it
hits one of the SSHFS mounts where the connection has dropped it locks
up there. Normally fuse can reconnect in the background but this doesn't
happen with rdesktop.
The interesting bit of strace is below:

and thats where it hangs. If I ensure all mounts are ok before running
rdesktop there is no problem.
Please let me know if you need any more information.
