Reproducible: Always




Might be related to bug #347344.

Comment 1 Christoph Feck 2016-06-13 16:28:04 UTC

Was the crash reproducible? If yes, does it still happen after bug 347344 was fixed?

Comment 2 Alexander Potashev 2016-06-13 18:41:44 UTC

Not reproducible with Plasma 5.6.1 and KF 5.22 on Gentoo.
