What steps will reproduce the problem?
1. Select some text while composing an e-mail in GMail 
2. Hit Ctrl-K

What is the expected result?
Expect not to crash

What happens instead of that?
About 1 in 5 times renderer crashes.  But when a specific situation will provoke a crash, it tends to ALWAYS provoke a crash each time I retry.

Sadly something seems broken with crash symbols on Linux right now, so all the crash reports are pretty useless.  Here are some of my recent crash IDs:

UserAgentString: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3080.5 Safari/537.36

I know I should try to download the official symbols and get a proper crash stack myself, but that's such a pain and I don't have time right now.
