Bug#625968: krfb freezes when moving local window from remote machine; left mouse button is disabled

I just found out that this issue is not really a problem if there is a
local user present in front of the server machine who can click a mouse
button or otherwise stop moving that window, however this has to happen
as long as the VNC connection is still active. However, in my use case,
there is nobody sitting in front of my computer who could do this and I
don't want to come home just to release a mouse button.

I have also found out that this issue is only happening with kwin. If I
replace kwin with metacity, everything is fine.

Mailer: reportbug 4.12.6

Package: krfb
Version: 4:4.4.5-2
Severity: important

When I try to move a window on my computer from a remote machine using krfb and
krdc, krfb freezes. This has the following results:
- I'm loosing my VNC connection.
- I cannot reconnect (killing krfb and waiting for krfb being restarted by a
script that I wrote for this purpose doesn't help either)
- The left mouse button remains "pressed" even if I kill krfb via SSH
- I can only stop moving the window that I wanted to move by clicking the right
mouse button (I have to do this locally)
- The left mouse button remains broken until I restart the X server.

I apologize if this has already been filed, but reportbug doesn't let me read
the bugs that have already been filed when my left mouse button is broken.
