--- Comment #4 from Mark <magpie...@gmx.com> --- Hi Michael and g'day again Leslie, Leslie, I can confirm at least that if main window is hidden when burning, it never re-appears after closing the burning dialog even though k3b is still running. This has always been the case in the Qt5 version (for me). Michael, here is some info to help make a detailed backtrace. Un-install the openSUSE package before beginning. Firstly, you'll need to download and compile k3b with debugging information. In a terminal, run the following: git clone https://github.com/KDE/k3b.git cd k3b mkdir build-debug cd build-debug cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_C_FLAGS=-ggdb -DCMAKE_CXX_FLAGS=-ggdb -DK3B_DEBUG=on -Wno-dev .. make -j4 sudo make install Now, start the debugging session by running: gdb k3b When loaded you'll have a prompt (gdb). Type (no quote marks) 'run' to start k3b then use k3b normally until you trigger the segfault. Go back to the (gdb) prompt and type 'backtrace'. Copy the output from this into your bug report. Now type 'detach' so that gdb closes the application then type 'quit' to exit gdb. Mark -- You are receiving this mail because: You are watching all bug changes.
