By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

Patch of fixing for crashes after the client disconnecting.

KRFB crushes just the client disconnect.

I have seen this behavior long ago but it was mysterious.

Currently, on Debian 9, the behavior is stable reproducible.

After observing I have seen that there is called a function of the thread exiting but for main thread of the process.

Then the fixing is just natural exiting the process.

Hi Roman, 
if it is easy to reproduce, can you briefly described the required steps? That will help in testing. Thanks.

1. Connect to the configured KRFB from KRDC.
2. Close the KRDC session.
3. 1...2 seconds and I have the crash with the crash preparing dialog.

The patch fixes the behavior, which is critical one if I connect to very remote host.

krfb-crash_at_disconnect.patch

KRFB also crashes during exiting on 14.1.0 with bad updation to libvnc.
So, this patch was updated to the bad libvnc.
