miro freezes screen

I'm having problems with context menus.

I inadvertently added a podcast as source. Trying to right-click the podcast under sources, miro tries to load the podcast as source, fails, and freezes. The mouse is moving, but I don't get out of the context menu, so none of my keys is working. `Alt`, `Super`, etc. don't work.

I don't need a podcast as source to reproduce this bug. Clicking myself through the menus / context menus while downloading a new podcast, for example, leaves miro freezing inside a menu, disabling all mouse and keyboard action.

(Is there a way to remove sources manually?)

I resolve the issue by doing "pkill miro" out of ttyx (Ctrl+Alt+Fx does work)...
