This question has been asked before, but went unanswered once, and was closed once for being apparently off-topic. So opening this again.
I installed alacarte and deleted a duplicate entry for Xtreme Download Manager. Since then, the launcher crashes and restarts when I type to search an app.
Any way to undo this change? I tried reinstalling wingpanel but didn't seem to help.
Any way I can gather logs and post here for help?
