Sublime text unusual title

Not sure how it could happen, but some process must have either created- or edited the local sublime-text.desktop file.

How to solve?

If you installed Sublime Text globally (and thus the file /usr/share/applications/sublime-text.desktop exists) simply remove the local one:

rm ~/.local/share/applications/sublime-text.desktop

and log out/in to make Unity find the global one.

If /usr/share/applications/sublime-text.desktop does not exist, open the local one:

gedit ~/.local/share/applications/sublime-text.desktop

and look for the first line, starting with Name=. Then replace the line by:

Name=Sublime Text
