Opening https://duckduckgo.com/ makes WebKitGtk-2.15.90 crash. Previous versions work. I get messages like this one: segfault at 227 ip 00007fa2bd1dd8bb sp 00007ffd08bc93a0 error 4 in libjavascriptcoregtk-4.0.so.18.5.4[7fa2bc6db000+f66000]
I'm a day or two behind 2.15.90 but it works for me. Stacktrace needed, please.
It seems this was introduced in r212618, tha was rolled out in r212665 and re-landed in r212692. Merged all that in 2.16 branch and it doesn't crash anymore.
