Comment #1 on issue 696 by pekka.klarck: Robot IDE fails to start
http://code.google.com/p/robotframework/issues/detail?id=696
This is a RIDE issue and should be reported to
http://code.google.com/p/robotframework-ride/. Please also report the RIDE
version you are using, and did you update RIDE or did this happen without
any changes. I'll leave this into Pending state in this tracker but this
will be closed soon.
You can most likely fix this by removing the settings file [1], but I'd
anyway like to know why this happens.
