** Description changed:
Binary package hint: mlview
Crashed after editing an XML 1.0/XHTML2+MathML document, apparently no data loss. trace is very long, starts with:
mlview-debug: in void mlview::PluginPriv::load() : in file mlview-plugin.cc : line 72 : condition (module) failed; raising exception
mlview-debug: in void mlview::PluginManager::load_all_plugins_from_default_plugins_dir() : in file mlview-plugin-manager.cc : line 106 : catched exception: Assertion failed
mlview-debug: in MlViewStatus mlview::SourceView::set_default_language() : in file mlview-source-view.cc : line 539 : mime_type: application/xhtml+xml
mlview-debug: in MlViewStatus mlview::SourceView::set_language_from_mime_type(const mlview::UString&) : in file mlview-source-view.cc : line 515 : language associated to 'application/xhtml+xml'mime type: 0
mlview-debug: in MlViewStatus mlview::SourceView::set_language_from_mime_type(const mlview::UString&) : in file mlview-source-view.cc : line 522 : falling back to the language associated tomime type 'text/xml'
mlview-debug: trying ro recon key: %x; mod & default mod mask:%x ...
: in file mlview-kb-eng.cc: line 395: (MlViewStatus mlview_kb_eng_lookup_a_key_binding(MlViewKBEng*, const MlViewKeyInput*, gint, MlViewKBDef**))
mlview-debug: Current key in lookup sequence: %x, modifier & default_mode_mask: %x
: in file mlview-kb-eng.cc: line 417: (MlViewStatus mlview_kb_eng_lookup_a_key_binding(MlViewKBEng*, const MlViewKeyInput*, gint, MlViewKBDef**))
mlview-debug: didn't find keybinding
the rest of the trace seems very similar to this last one
