In the latest version (184.108.40.206) new projects will display an error about symbol table not being available while it is generating the table.
The error can be ignored while the symbol tables generate. However, once the project is 'ready', attempting to open a class and click around a bit causes the IDE to crash.
Rolling back to 220.127.116.11, this issue is no longer present.
It doesn't appear to affect projects that were already existing pre-update.
