If the preferences.xml file is broken, inkscape displays a modal dialog with a warning at the launch. Still there is no parent window yet for the warning message. As warning message dialog has properties _NET_WM_STATE_MODAL and _NET_WM_STATE_SKIP_TASKBAR, it is not shown on the task bar, it blocks inkscape for starting up till user clicks on OK. The problem is - if window manager prevents focus stealing, the dialog is created behind other windows and _NET_WM_STATE_SKIP_TASKBAR prevents it from appearing on the task bar thus user has no idea that such dialog exists! It can be discovered only by an accident - when using alt+tab or minimizing any other windows. As the dialog provides only a warning, it should not be modal. If warnings modality is kept, it should not have _NET_WM_STATE_SKIP_TASKBAR property set.
Steps to reproduce with inkscape-0.48.4-r1:
.config/inkscape/preferences.xml && touch .config/inkscape/preferences.xml
start Firefox or any other application and maximize it
start inkscape
