Comment 1 Peter Penz 2012-03-25 16:20:36 UTC
Thanks for the report, sadly the backtrace does not give enough hints to know where the error occured. Do you probably have enabled the Subversion, Git, ... or any other plugin for Dolphin?
Comment 2 Tom 2012-03-25 18:49:35 UTC
I don't have kdesdk-dolphin-plugins installed, and I don't remember enabling any plugins.
Comment 3 Peter Penz 2012-03-25 19:02:10 UTC
Hm... Ok, then we simply have to wait until a similar backtrace from other users comes in. Probably they found per accident a different approach that will trigger this issue.
