• Component: WebKitGTK
• Status: RESOLVED FIXED

[Zan Dobersek]

The following two tests started crashing on the GTK debug builds:
storage/indexeddb/factory-basics-workers.html
storage/indexeddb/transaction-error.html

Crashes started occurring in the following commit range, with r146540 being the most likely cause of regression:
http://trac.webkit.org/log/?verbose=on&rev=146545&stop_rev=146535
http://trac.webkit.org/changeset/146540
