dialogs during reconnect

[uli42]

From a session based on an self-compiled nx 3.5.0.32 (with some small changes, to the line numbers might differ) I see this on reconnect (I have also seen this on newer versions, but I cannot offer a backtrace, so let's use this for now):

#0  0x00007f2ce6038933 in __select_nocancel () from /lib64/libc.so.6

It looks like there's a workflow problem here. Some code tries to present a dialog when a problem during reconnect arises. But as there session has not been reconnected yet the dialog cannot be shown (or maybe it is shown inside nxagent but (naturally) invisible for the user so the user is unable to properly answer the dialog - need to investigate)

A solution could be to hanlde over the task of displaying a dialog to the nxproxy. Another solution could be not to wait for the dialog to be answered. And the obvious solution is not to show any dialogs during reconnect but only log that situation.

I doubt the version number above is correct...
