Predator and CL could not provide any possible suspects.

Using Code Search for the file, "input_method_auralinux.cc" suspecting the below Cl might have caused this issue

Suspect CL: https://chromium.googlesource.com/chromium/src/+/65eaaf4ff757a827e5477b123fd772d7da49b78a

yhanada@ -- Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Thanks!

The CL mentioned in comment 2 does just renaming the methods. I don't think it causes the issue.
