I upgraded my laptop to Trusty Tahr today.
One thing that didn’t work immediately was the Crashplan GUI. It crashes with a SIGSEGV. In summary “C [libsoup-2.4.so.1+0x6c2a1] soup_session_feature_detach+0x11”.
I managed to find this bug, and then I found /usr/local/crashplan/bin/run.conf which has a variable GUI_JAVA_OPTS.
Adding ” -Dorg.eclipse.swt.browser.DefaultType=mozilla” to the end of that variable, and the GUI starts without fail. Win!
