Bug description
When going into the advanced preferences section, if you enter invalid inputs, the application will crash.
In order to fix this, you have to delete
Here is an example:
editor.tabs.size=2/
I accidentally typed in a "/" and the program crashed. But deleting that entry from preferences.txt fixed it.
Steps to reproduce this
-
Go to advanced settings
-
Go to a text field input (like tab size) and enter non-numeric input
-
This will create a parse error and crash the application
