summary: sometimes cannot cancel or close the file transfer dialog when agent disconnect

version: virt-viewer-6.0-2017021715110.spice.nightly.fc25.x86_64

steps:

Prepare a vm which has not enough disk space for a iso file transfer.
transfer the iso file to the vm.
during the iso file transferring, select and drag the other 5 (the more the better) files into the vm.
redo step 3 several times to increase the file transferring counts.

Result: the agent will fail during transferring and the transferring dialog can't be closed/cancelled.
