I run the latest WebStorm on 64 bit Linux using Oracle Java 1.8.25. Half of the time I enter WebStorm I get:

Thank you for reporting.

What version of plugin do you use ?

[blakemcbride]

WebStorm version 9.0.3. The problem started after the last .gitignore update. Currently it seems the .gitignore version is 1.0 but I am getting a message to do another update. Now I have 1.0.2. No startup error this time. I'll let you know if I get the error again. Thanks!

Issue has been already fixed with #84

Thanks and good luck !
