CrashPlan client closes in some Linux installations

Affects

CrashPlan Client 3.5.3 - 3.6.4

Linux, running GNOME 3, have GNOME 3 repositories added, and/or have installed libwebkitgtk-dev

Summary

The desktop client fails to launch. The splash screen appears for a second or two, and then disappears without error.

Diagnosis

The ui_output.log file within usr/local/crashplan/log (for openSUSE) displays:

Root Cause

This is a bug in libsoup:

Wordaround

Edit /var/local/crashplan/bin/run.conf
Navigate to the end of the GUI_JAVA_OPTS section
Add this line, inside the quotes:

-Dorg.eclipse.swt.browser.DefaultType=mozilla

Example:

SRV_JAVA_OPTS="-Dfile.encoding=UTF-8 -Dapp=CrashPlanService -DappBaseName=CrashPlan -Xms20m -Xmx1024m -Djava.net.preferIPv4Stack=true -Dsun.net.inetaddr.ttl=300 -Dnetworkaddress.cache.ttl=300 -Dsun.net.inetaddr.negative.ttl=0 -Dnetworkaddress.cache.negative.ttl=0 -Dc42.native.md5.enabled=false"
GUI_JAVA_OPTS="-Dfile.encoding=UTF-8 -Dapp=CrashPlanDesktop -DappBaseName=CrashPlan -Xms20m -Xmx512m -Djava.net.preferIPv4Stack=true -Dsun.net.inetaddr.ttl=300 -Dnetworkaddress.cache.ttl=300 -Dsun.net.inetaddr.negative.ttl=0 -Dnetworkaddress.cache.negative.ttl=0 -Dc42.native.md5.enabled=false -Dorg.eclipse.swt.browser.DefaultType=mozilla"

After saving the file, the CrashPlan Desktop should launch properly.

This article was taken from the Code42 CrashPlan forums and has been slightly ammended to work with openSUSE 13.2 where I'm having the problem. Has been tested and works.
