Hi @mniestroj please next time either you mark as false positive in Coverity (with the justification) or ask someone to do it, otherwise this issue will automatically be re-opened in the next scan. I've done it for this one though.

@ceolin Thanks for letting me know. How can I get Coverity account/permission to do that next time?
