Open KRDC 2. Click on the saved connection 3. Pasted the password I copied from Konsole During the paste, I noticed there's much more symbols than in the password itself. When I re-open the KRDC and try again, it works The crash can be reproduced every time. -- Backtrace: Application: KRDC (krdc), signal: Aborted [KCrash Handler] #4 0x00007eff176df9d5 in raise () from /lib64/libc.so.6 #5 0x00007eff176c88a4 in abort () from /lib64/libc.so.6 #6 0x00007eff17b0648f in QMessageLogger::fatal(char const*, ...) const () from /lib64/libQt5Core.so.5 #7 0x00007eff17b06cfb in QThread::~QThread() [clone .cold] () from /lib64/libQt5Core.so.5 #8 0x00007eff0433c118 in VncView::~VncView() () from /usr/lib64/qt5/plugins/krdc/libkrdc_vncplugin.so #9 0x00007eff0433c189 in VncView::~VncView() () from /usr/lib64/qt5/plugins/krdc/libkrdc_vncplugin.so #10 0x00007eff17cfe93a in QObjectPrivate::deleteChildren() () from /lib64/libQt5Core.so.5 #11 0x00007eff1895e246 in QWidget::~QWidget() () from /lib64/libQt5Widgets.so.5 #12 0x00007eff1895e59d in QWidget::~QWidget() () from /lib64/libQt5Widgets.so.5 #13 0x00007eff17cfe93a in QObjectPrivate::deleteChildren() () from /lib64/libQt5Core.so.5 #14 0x00007eff1895e246 in QWidget::~QWidget() () from /lib64/libQt5Widgets.so.5 #15 0x00005649d529e6fd in RemoteViewScrollArea::~RemoteViewScrollArea() () #16 0x00007eff17cfeb21 in QObject::event(QEvent*) () from /lib64/libQt5Core.so.5 #17 0x00007eff18a0c6f2 in QFrame::event(QEvent*) () from /lib64/libQt5Widgets.so.5 #18 0x00007eff18921ec3 in QApplicationPrivate::notify_helper(QObject*, QEvent*) () from /lib64/libQt5Widgets.so.5 #19 0x00007eff17cd6bd8 in QCoreApplication::notifyInternal2(QObject*, QEvent*) () from /lib64/libQt5Core.so.5 #20 0x00007eff17cd98c7 in QCoreApplicationPrivate::sendPostedEvents(QObject*, int, QThreadData*) () from /lib64/libQt5Core.so.5 #21 0x00007eff17d23c27 in postEventSourceDispatch(_GSource*, int (*)(void*), void*) () from /lib64/libQt5Core.so.5 #22 0x00007eff15a4aa9f in g_main_context_dispatch () from /lib64/libglib-2.0.so.0 #23 0x00007eff15a9ca98 in g_main_context_iterate.constprop () from /lib64/libglib-2.0.so.0 #24 0x00007eff15a47e73 in g_main_context_iteration () from /lib64/libglib-2.0.so.0 #25 0x00007eff17d236f3 in QEventDispatcherGlib::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) () from /lib64/libQt5Core.so.5 #26 0x00007eff17cd557b in QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) () from /lib64/libQt5Core.so.5 #27 0x00007eff18b21f8f in QDialog::exec() () from /lib64/libQt5Widgets.so.5 #28 0x00007eff04341150 in VncView::qt_static_metacall(QObject*, QMetaObject::Call, int, void**) [clone .part.0] () from /usr/lib64/qt5/plugins/krdc/libkrdc_vncplugin.so #29 0x00007eff17cfed1e in QObject::event(QEvent*) () from /lib64/libQt5Core.so.5 #30 0x00007eff18921ec3 in QApplicationPrivate::notify_helper(QObject*, QEvent*) () from /lib64/libQt5Widgets.so.5 #31 0x00007eff17cd6bd8 in QCoreApplication::notifyInternal2(QObject*, QEvent*) () from /lib64/libQt5Core.so.5 #32 0x00007eff17cd98c7 in QCoreApplicationPrivate::sendPostedEvents(QObject*, int, QThreadData*) () from /lib64/libQt5Core.so.5 #33 0x00007eff17d23c27 in postEventSourceDispatch(_GSource*, int (*)(void*), void*) () from /lib64/libQt5Core.so.5 #34 0x00007eff15a4aa9f in g_main_context_dispatch () from /lib64/libglib-2.0.so.0 #35 0x00007eff15a9ca98 in g_main_context_iterate.constprop () from /lib64/libglib-2.0.so.0 #36 0x00007eff15a47e73 in g_main_context_iteration () from /lib64/libglib-2.0.so.0 #37 0x00007eff17d236f3 in QEventDispatcherGlib::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) () from /lib64/libQt5Core.so.5 #38 0x00007eff17cd557b in QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) () from /lib64/libQt5Core.so.5 #39 0x00007eff17cdd1b4 in QCoreApplication::exec() () from /lib64/libQt5Core.so.5 #40 0x00005649d529d3c0 in main () [Inferior 1 (process 1832100) detached] Possible duplicates by query: bug 424911, bug 423951, bug 423132, bug 417285, bug 414922.

Okay so I understand how to reproduce it. What I really had in my clipboard was an image which I managed to successfully paste as a VNC password. After that I got a message "VNC closed the connection", but the password window for some reason reappeared. Right after that KRDC crashed.
When you say "pasted as VNC password", can you clarify exactly where you pasted it? A screenshot would probably help
>When you say "pasted as VNC password", can you clarify exactly where you pasted it? > >A screenshot would probably help Sure. Here's the window asking for the password: https://i.imgur.com/GkME4Cz.png It appears when I double-left-click the saved connection. So, as a reproduction, I can do these steps: 1. Open a picture in Gwenview 2. Copy the picture to the clipboard via pressing Ctrl-C in Gwenview window 3. Paste this picture via Ctrl-V to the only text input field in the window from the screenshot The image appears there as lots of (hidden) characters. Then, if I press "OK", I'll get an error about invalid password *and* the window from the screenshot will reappear (which doesn't happen if I simply type the incorrect password). Right after that KRDC crashes.
I can not make it crash, can you please run krdc from the command line? When it crashes it seems like it's writing something to the command line, can you paste it here?
Sorry, I can't reproduce it anymore. If I get to this issue again, I'll reopen this task.
So I could reproduce this again. For some reason it happens only with one of my connections while doesn't happen with the other. I collected the output of the krdc while it was crashing and here it is: ❯ krdc KRDC: rfbInitClient failed KRDC: "VNC server closed connection." QThread: Destroyed while thread is still running KCrash: Application 'krdc' crashing... KCrash: Attempting to start /usr/libexec/drkonqi [1] + 1728121 suspended (signal) krdc
Not super useful, something is not working as it should but doesn't really give much information, without a way to reproduce it, i don't personally have time to investigate it, maybe someone else does
