Package: kylin-video Version: 3.1.4-1 Severity: important Dear Maintainer,
kylin-video crashes with SIGSEGV during startup when its Qt5 executable calls the Qt6 build of libukui-log4qt. The crash occurs during logging initialization, before the main window appears. Steps to reproduce: 1. Install kylin-video 3.1.4-1 with the Qt6-based libukui-log4qt1. 2. Run /usr/bin/kylin-video-new without any arguments. Actual result: The application crashes with SIGSEGV in initUkuiLog4qt(QString). The backtrace shows: #0 ?? () from libQt6Core.so.6 #1 QString::toLower_helper(QString const&) () from libQt6Core.so.6 #2 initUkuiLog4qt(QString) () from libukui-log4qt.so.1 #3 main () The executable links against Qt5, while libukui-log4qt.so.1 links against Qt6. Both sides use the same mangled symbol for initUkuiLog4qt(QString), but QString is not ABI-compatible between Qt5 and Qt6. Expected result: kylin-video should start normally without crashing during logging initialization.
