There is a quick fix for it. The crash is caused due to a window that doesn't set focus to another window when it dies and thus makes the Blackbox::focused_window point to a dead BlackboxWindow. This is fixed by adding these lines in the Window.cc in BlackboxWindow::~BlackboxWindow row 446 :
if (client.transient_for) blackbox->setFocusedWindow(client.transient_for); and for Fluxbox 0.1.4 in Window.cc in FluxboxWindow::~FluxboxWindow row 506 : if (client.transient_for) fluxbox->setFocusedWindow(client.transient_for); This is a quickfix for it and these lines should later be in Workspace::removeWindow(...) > I am using Sylpheed Claws 0.6.5. for e-mail.
