Comment 1 Andrei Slavoiu 2017-12-22 01:04:52 UTC 
After closing the crash handler and starting a new instance of Konqueror (the restart option in the crash handler didn't appear to do anything) my previous browsing session was restored correctly an also a browsing session from a few months ago (many reboots since then) was restored, together with a bogus session to a malformed url.
