I still get an assertion failure, using hugin version 2014.0.0+dfsg-2 (the system Debian jessie/testing, fully updated right now).
ASSERT INFO: /usr/include/wx-3.0/wx/strvararg.h(456): assert "(argtype & (wxFormatStringSpecifier<T>::value)) == argtype" failed in wxArgNormalizer(): format specifier doesn't match argument type BACKTRACE: [1] CPImageCtrl::setCtrlPoint(HuginBase::ControlPoint const&, bool) [2] CPEditorPanel::UpdateDisplay(bool) [3] CPEditorPanel::setRightImage(unsigned int) [4] PreviewLayoutLinesTool::MouseButtonEvent(wxMouseEvent&) [5] ToolHelper::MouseButtonEvent(wxMouseEvent&) [6] wxAppConsoleBase::CallEventHandler(wxEvtHandler*, wxEventFunctor&, wxEvent&) const [7] wxEvtHandler::ProcessEventIfMatchesId(wxEventTableEntryBase const&, wxEvtHandler*, wxEvent&) [8] wxEventHashTable::HandleEvent(wxEvent&, wxEvtHandler*) [9] wxEvtHandler::TryHereOnly(wxEvent&) [10] wxEvtHandler::ProcessEventLocally(wxEvent&) [11] wxEvtHandler::ProcessEvent(wxEvent&) [12] wxEvtHandler::SafelyProcessEvent(wxEvent&) [13] g_closure_invoke [14] g_signal_emit_valist [15] g_signal_emit [16] gtk_propagate_event [17] gtk_main_do_event [18] g_main_context_dispatch [19] g_main_loop_run [20] gtk_main [21] wxGUIEventLoop::DoRun() [22] wxEventLoopBase::Run() [23] wxAppConsoleBase::MainLoop() [24] wxEntry(int&, wchar_t**) [25] main [26] __libc_start_main [27] _start I got it when clicking on one of the lines between two photos in the 'Layout' tab. I also got assertion failures when clicking the 'Align' tab before, but somehow they disappeared after running apt-get autoremove (I still have the backtrace if needed). — Ayke
