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
