Hello, After a recent qt update I have qt-related problem with different applications: Cannot mix incompatible Qt library (5.15.7) with this library (5.15.8) Among others there is matplotlib. Steps to reproduce: Run gdb with python in type in prompt: import matplotlib.pyplot as plt subplots = plt.subplots() [New Thread 0x7fffeeb7b6c0 (LWP 3332791)] [New Thread 0x7fffecf586c0 (LWP 3332792)] [New Thread 0x7fffe7fff6c0 (LWP 3332793)] [New Thread 0x7fffe77fe6c0 (LWP 3332794)] [New Thread 0x7fffe6ffd6c0 (LWP 3332795)] Cannot mix incompatible Qt library (5.15.7) with this library (5.15.8) Thread 6 "QDBusConnection" received signal SIGABRT, Aborted. backtrace: (gdb) bt #0 0x00007ffff78b400c in () at /usr/lib64/libc.so.6 #1 0x00007ffff7866572 in raise () at /usr/lib64/libc.so.6 #2 0x00007ffff78504b2 in abort () at /usr/lib64/libc.so.6 #3 0x00007ffff2e91d6d in qt_message_output(QtMsgType, QMessageLogContext const&, QString const&) [clone .cold] () at /usr/lib64/libQt5Core.so.5 #4 0x00007ffff2ea838f in () at /usr/lib64/libQt5Core.so.5 #5 0x00007fffeec61773 in QDBusAbstractInterfacePrivate::QDBusAbstractInterfacePrivate(QString const&, QString const&, QString const&, QDBusConnection const&, bool) () at /usr/lib64/libQt5DBus.so.5 #6 0x00007fffeec62989 in QDBusAbstractInterface::QDBusAbstractInterface(QString const&, QString const&, char const*, QDBusConnection const&, QObject*) () at /usr/lib64/libQt5DBus.so.5 #7 0x00007fffeec49769 in QDBusConnectionInterface::QDBusConnectionInterface(QDBusConnection const&, QObject*) () at /usr/lib64/libQt5DBus.so.5 #8 0x00007fffeec4690a in QDBusConnectionPrivate::createBusService() () at /usr/lib64/libQt5DBus.so.5 #9 0x00007fffeec47ce1 in QDBusConnectionManager::executeConnectionRequest(QDBusConnectionManager::ConnectionRequestData*) () at /usr/lib64/libQt5DBus.so.5 #10 0x00007ffff30a4b14 in QObject::event(QEvent*) () at /usr/lib64/libQt5Core.so.5 #11 0x00007ffff307a2f5 in QCoreApplication::notifyInternal2(QObject*, QEvent*) () at /usr/lib64/libQt5Core.so.5 #12 0x00007ffff307d6c3 in QCoreApplicationPrivate::sendPostedEvents(QObject*, int, QThreadData*) () at /usr/lib64/libQt5Core.so.5 #13 0x00007ffff30ca8f3 in postEventSourceDispatch(_GSource*, int ( )(void ), void*) () at /usr/lib64/libQt5Core.so.5 #14 0x00007ffff46fb208 in g_main_context_dispatch () at /usr/lib64/libglib-2.0.so.0 #15 0x00007ffff46fb738 in g_main_context_iterate.constprop () at /usr/lib64/libglib-2.0.so.0 #16 0x00007ffff46fb7cc in g_main_context_iteration () at /usr/lib64/libglib-2.0.so.0 #17 0x00007ffff30ca3f6 in QEventDispatcherGlib::processEvents(QFlags QEventLoop::ProcessEventsFlag ) () at /usr/lib64/libQt5Core.so.5 #18 0x00007ffff3078ddb in QEventLoop::exec(QFlags QEventLoop::ProcessEventsFlag ) () at /usr/lib64/libQt5Core.so.5 #19 0x00007ffff2eca022 in QThread::exec() () at /usr/lib64/libQt5Core.so.5 #20 0x00007fffeec454c7 in QDBusConnectionManager::run() () at /usr/lib64/libQt5DBus.so.5 #21 0x00007ffff2ecb267 in QThreadPrivate::start(void*) () at /usr/lib64/libQt5Core.so.5 #22 0x00007ffff78b232a in () at /usr/lib64/libc.so.6 #23 0x00007ffff7931d0c in () at /usr/lib64/libc.so.6 I use Gentoo Linux, current kernel version 6.1.13.
