Once I go to ~/.kde/share/config/dolphinrc and turn VersionControl=Dropbox into VersionControl=null, Dolphin starts again with no problem.

kdebug output and dump

I manage to get this to happen even *without* restarting Dolphin. It occurs after a moment or so when opening Dolphin. I'm assuming that's KIO attempting to communicate with Dropbox then hitting this.
Comment 3 Frank Reininghaus 2014-04-08 06:27:10 UTC 
Thanks for the bug report! This looks pretty much like a crash which has been fixed recently. (See also the duplicate bug 332983, which was also about Dolphin crashing reproducibly on startup, and which the reporter confirmed to be fixed by the patch).
