            Bug ID: 393566
           Summary: crashes when closing tab
           Product: akregator
           Version: GIT (master)
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: internal browser
          Assignee: kdepim-bugs at kde.org
          Reporter: kollix at aon.at
  Target Milestone: ---

Just with some recent changes (either in KDE-PIM sources or Qt 5.10) akregator
very often crashes e.g. on closing a tab.
That was not the case just a week or 2 ago, but now it's happening so often
that akregator is barely usable.
I assume it has to do with webengine, since I also encounter often crashes in
kmail since.
