With enabled -Woverloaded-virtual gcc warning (see http://lists.freedesktop.org/archives/libreoffice/2011-March/009567.html), canvas exposed a nasty clash between WeakComponentImplHelper::disposing and XEventListener::disposing. Fixed by overriding *once* in baseclass, and then calling disambiguated, renamed methods.
