Application: kopete (1.13.0) Qt Version: 5.9.3 Frameworks Version: 5.46.0 Operating System: Linux 4.13.0-41-generic x86_64 Distribution: KDE neon LTS User Edition 5.12 -- Information about the crash: - What I was doing when the application crashed: I'm using kopete to communicate through our company local jabber sever. I have opened several tabs (chats) with different persons. After several messages (sending/recieving) i changed to another tab. But when i wrote message to this chat - i can't send my message due to inactivity of "Send" button. So, the first issue, that "Send" button does not become enabled after text typing in chat window. Also my send shortcut key doesn't work. After that - i'm trying to reopen my chat window, to "fix" this issue. But after close this chat window my kopete crashes. The crash can be reproduced every time. -- Backtrace: Application: Kopete (kopete), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Having exact the same problem on opensuse 15.1 with kopete 1.13 KDE Frameworks 5.55.0 Qt 5.9.7
SOFTWARE/OS VERSIONS Operating System: Slackware Linux -current KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.78.0 Qt Version: 5.15.2 Kernel Version: 5.10.14 OS Type: 64-bit Processors: 8 × AMD Ryzen 7 4700U with Radeon Graphics Memory: 15,0 GiB of RAM Graphics Processor: AMD RENOIR I can reproduce this issue every time a chat window gets closed. It only happens on a plasma wayland session; no crash under x11. The crash signature is the same: #4 0x00007f0fecb35c50 in QScrollArea::widget() const () from /usr/lib64/libQt5Widgets.so.5 #5 0x00007f0fc325bf79 in KHTMLView::contentsHeight() const () from /usr/lib64/libKF5KHtml.so.5 #6 0x00007f0fd40989d3 in ChatMessagePart::slotScrollView() () from /usr/lib64/libkopetechatwindow_shared.so.1
I debugged this issue a bit. There's a workaround, just disabling "Input auto-resize" from the "Format" menu avoids the crash when closing the chat window. The crash is due to KopeteRichTextWidget triggering a size recalc on the chatview of the window that has just been closed; this leads to a call to ChatMessagePart::keepScrolledDown() to ensure the view is scrolled down to the last message. Here's the backtrace up to the method emitting the signal: #0 ChatMessagePart::keepScrolledDown (this=0xd76ba0) at /home/fabio/prj/kopete/kopete/chatwindow/chatmessagepart.cpp:650 #1 0x00007fffd81c4324 in ChatView::slotRecalculateSize (this=0x10bda20, difference=0) at /home/fabio/prj/kopete/kopete/chatwindow/chatview.cpp:488 #2 0x00007fffd81bf0ab in ChatView::qt_static_metacall (_o=0x10bda20, _c=QMetaObject::InvokeMetaMethod, _id=25, _a=0x7fffffffbf30) at /home/fabio/prj/kopete/buid/kopete/chatwindow/kopete_chatwindow_autogen/EWIEGA46WW/moc_chatview.cpp:275 #3 0x00007ffff55d4845 in ??
