Comment 1 Kevin Funk 2016-04-06 18:48:52 UTC 
Are you sure you don't have multiple versions of KDevelop installed? This looks like an ABI issue, backtrace indicates you're loading plugins from an older install.
Comment 2 Vladimir Olovyannikov 2016-04-06 19:15:04 UTC 
You are right.
I should have cleaned before building of the new ver.
I will set the status as resolved.

Thanks,
Vladimir
